The won't-close diagnosis has a specific hierarchy in Mccormick. Sensor first in Mccormick, SC. Down-travel limit second in Mccormick. Physical obstruction third in Mccormick, SC. Spring imbalance and force limit interaction fourth in Mccormick. Opener logic board fifth in Mccormick, SC. Working through this hierarchy in order matters because each step is faster and less expensive than the next in Mccormick. A sensor misalignment resolved in the first step costs $50 to $100 in Mccormick, SC. A sensor replacement found in the second part of the first step costs $75 to $150 in Mccormick. A limit adjustment found in the second step costs $50 to $100 in Mccormick, SC. A logic board replacement found in the fifth step costs $150 to $350 in Mccormick. Skipping to the fifth step when the first step would have resolved it costs four times as much for the same result in Mccormick, SC. EZ Open follows the hierarchy in order on every won't-close call in Mccormick.

A sensor replacement performed before checking the limit settings may resolve the won't-close symptom if the sensor was the cause and may not if the limit was the actual cause in Mccormick. A logic board replacement performed before checking the sensor may resolve it if the board was the cause and will definitely not resolve it if the sensor or limit was the cause in Mccormick, SC. The diagnostic hierarchy exists because it works from the most common and least expensive causes to the least common and most expensive in Mccormick. EZ Open follows it in order because it produces the correct diagnosis at the minimum necessary cost in Mccormick, SC.
A garage door that won't close removes the physical security barrier between the exterior and the garage in Mccormick, SC. The garage is one of the most common residential entry points for break-ins in Mccormick. An open garage eliminates the locked door barrier that a closed and secured garage door provides in Mccormick, SC. Everything in the garage is immediately accessible in Mccormick. In homes where the garage connects to the interior through a door, an open garage provides effective access to the home in Mccormick, SC. This is the most urgent consequence of a door that won't close and the reason EZ Open responds to won't-close calls with the same urgency as emergency calls in Mccormick.
EZ Open's won't close service covers complete diagnostic hierarchy assessment in the correct sequence, sensor LED status check and alignment or replacement where indicated, limit and force setting verification and adjustment where needed, physical obstruction assessment where sensor and limit checks haven't identified the cause, spring balance assessment where force limit interaction is suspected, opener component assessment where hardware causes have been ruled out, correct repair for the confirmed cause, and complete close cycle verification with beam interruption test before we leave in Mccormick.

The safety sensor system is involved in the overwhelming majority of garage door won't-close situations in Mccormick, SC. EZ Open checks the sensor LED status immediately on arrival before any other assessment in Mccormick. Both sensor LED lights observed. Transmitter LED status. Receiver LED status in Mccormick, SC. Whether the LED states indicate misalignment, component failure, or correct alignment in Mccormick. If the sensor system is the cause, it's identified and addressed at the first step in the hierarchy in Mccormick, SC.
If the sensor LEDs are both solid and the sensor system is functioning correctly, EZ Open checks the down-travel limit setting in Mccormick. The down-travel limit tells the opener how far to travel in the closing direction before stopping in Mccormick, SC. A limit set too high stops the opener before the door reaches the floor, leaving a gap in Mccormick. This produces a door that doesn't fully close but doesn't reverse in Mccormick, SC. A limit setting adjustment is a quick calibration that resolves this cause immediately in Mccormick.
If the sensor and limit are both correct, EZ Open assesses the door path and floor level for a physical obstruction in Mccormick. An object in the path of the door at floor level. A damaged or compressed floor seal that catches on the floor surface before the door reaches the closed position in Mccormick, SC. Debris accumulation at the door threshold in Mccormick. These physical obstructions produce a reversal that appears identical to a sensor reversal but originates in physical contact rather than beam interruption in Mccormick, SC.
If no physical obstruction is found, EZ Open assesses spring balance in Mccormick, SC. A spring that's lost significant tension makes the door heavier on the closing cycle in Mccormick. The opener's closing force limit may trigger before the door reaches the floor if the door's effective closing resistance exceeds the limit setting in Mccormick, SC. This produces a door that stops short of the floor without reversing in Mccormick. Spring assessment and force limit calibration address this cause in Mccormick, SC.
If sensor, limit, physical obstruction, and spring balance are all confirmed as correct, EZ Open assesses the opener logic board for erratic closing behavior in Mccormick, SC. Random reversals without a consistent physical cause. Failure to initiate the close cycle despite correct inputs in Mccormick. Stopping mid-cycle at inconsistent points in Mccormick, SC. These symptoms without a consistent physical cause point to logic board involvement in Mccormick.
A sensor realignment at step one costs $50 to $100 in Mccormick. A logic board replacement at step five costs $150 to $350 in Mccormick, SC. If the sensor was the cause and the logic board was replaced without checking the sensor first, the homeowner paid $150 to $350 for a problem that would have cost $50 to $100 to resolve in Mccormick. Following the hierarchy in order means the cause is identified at the least expensive step that applies in Mccormick, SC.
The safety sensor system consists of a transmitter and a receiver mounted at the bottom of the door opening on each side in Mccormick, SC. The transmitter sends a continuous infrared beam to the receiver in Mccormick. When the receiver detects the full beam, it sends a continuous confirmation signal to the opener's logic board indicating a clear path in Mccormick, SC. The logic board will complete the closing cycle only while this confirmation signal is continuously present in Mccormick. Any interruption of the signal causes the logic board to reverse the door immediately in Mccormick, SC.
There are four possible LED states across the two sensors that EZ Open reads on arrival in Mccormick. Both LEDs solid indicates correct sensor alignment and function in Mccormick, SC. Receiver LED blinking, transmitter LED solid indicates sensor misalignment or a beam obstruction in Mccormick. Receiver LED off, transmitter LED solid indicates no power to the receiver, which points to a wiring fault or receiver failure in Mccormick, SC. Both LEDs off indicates no power to either sensor, which points to the sensor wiring connection at the opener control board in Mccormick.
A blinking receiver LED indicates the receiver isn't detecting the full beam from the transmitter in Mccormick, SC. This can mean the sensor bracket has rotated out of the correct alignment or the sensor component itself has failed in Mccormick. To distinguish between the two, EZ Open gently adjusts the receiver bracket through its full range of angles while watching the LED in Mccormick, SC. If the LED becomes solid at any angle, the sensor is functional but misaligned in Mccormick. If the LED stays blinking through the full range of bracket adjustment, the sensor itself has failed and requires replacement in Mccormick, SC.
Direct sunlight contains infrared radiation at intensities that can overwhelm the receiver's ability to distinguish the transmitter's signal from the background in Mccormick. When direct sunlight hits the receiver lens at a specific angle, the receiver can't confirm the transmitter's beam against the solar infrared background in Mccormick, SC. The opener reverses the door exactly as it would for a misaligned sensor or a physical obstruction in Mccormick. A door that won't close only at specific times of day when the sun is at a particular angle is almost certainly experiencing solar interference in Mccormick, SC.
Sensor replacement is required when the receiver LED stays blinking through the full range of bracket adjustment with no obstruction between the sensors in Mccormick, SC. This confirms the receiver's internal photoelectric component has failed in Mccormick. Sensor replacement is also required when the LED is completely off indicating power supply failure at the sensor unit in Mccormick, SC. EZ Open carries replacement sensors compatible with all major opener brands in Mccormick.
The sensor bracket on one or both sensors has rotated away from the correct beam angle in Mccormick, SC. Physical contact from a person or object, vibration from door operation over time, or accidental contact during garage use are the most common causes in Mccormick. The receiver LED blinks or is dim rather than solid in Mccormick, SC. Bracket adjustment until the receiver LED becomes solid resolves misalignment in most cases in Mccormick.
A sensor component that has failed internally produces the same LED behavior as misalignment but doesn't resolve with bracket adjustment in Mccormick. The receiver LED stays blinking regardless of the bracket angle in Mccormick, SC. Replacement with a compatible sensor unit is required in Mccormick. EZ Open distinguishes between misalignment and failure through the bracket adjustment test before recommending any sensor replacement in Mccormick, SC.
The down-travel limit setting tells the opener when to stop the closing cycle in Mccormick, SC. A limit set too high stops the opener before the door reaches the floor in Mccormick. The door stops short of the floor without reversing in Mccormick, SC. This is often confused with a sensor fault but produces a distinctly different symptom, the door stops rather than reverses in Mccormick. A limit calibration adjustment resolves this cause immediately in Mccormick, SC.
An object in the door's path at floor level triggers the same reversal response as a misaligned sensor in Mccormick, SC. The door contacts the object before reaching the floor and the opener reverses in Mccormick. A floor mat that's shifted into the door path. A tool or piece of equipment near the door edge. Debris at the door threshold in Mccormick, SC. Removing the obstruction resolves the cause in Mccormick.
A spring that has lost significant tension produces a heavier door in Mccormick. The heavier door requires more closing force from the opener in Mccormick, SC. If the required closing force exceeds the opener's force limit setting, the opener stops before the door reaches the floor in Mccormick. This produces a door that stops short without reversing in Mccormick, SC. Spring assessment and replacement where indicated alongside force limit recalibration addresses this cause in Mccormick.
The low-voltage wiring connecting each sensor to the opener control board runs from the sensor bracket up the door frame and along the ceiling to the opener in Mccormick. Damage at any point along this run, from a staple that pierced the wire, a rodent that chewed through it, or physical disturbance that cut or kinked it, can produce sensor symptoms that appear identical to sensor failure or misalignment in Mccormick, SC. EZ Open inspects the complete wiring run where sensor LED behavior doesn't clearly indicate misalignment or component failure in Mccormick.
A logic board with a failing component can produce erratic closing behavior including random reversals at inconsistent points in the close cycle, failure to initiate the close cycle despite correct sensor and limit settings, and stopping mid-cycle for no identifiable physical reason in Mccormick. Logic board faults are the least common cause of won't-close behavior and are the last step in the diagnostic hierarchy in Mccormick, SC. They're identified after sensor, limit, physical obstruction, and spring balance have been ruled out in Mccormick.
Both sensor LED lights observed on arrival in Mccormick, SC. LED state categorized into one of the four possible states in Mccormick. Diagnostic direction established from the LED state in Mccormick, SC.
Bracket adjustment test performed where receiver LED is blinking in Mccormick, SC. If LED becomes solid with adjustment, sensor realigned and locked in correct position in Mccormick. If LED stays blinking through full bracket range, sensor replaced with compatible unit in Mccormick, SC. Wiring assessed where LED is completely off in Mccormick.
Down-travel limit verified by observing where the door stops in the closing direction in Mccormick. Limit adjusted if the door stops before reaching the floor without reversing in Mccormick, SC. Force limit verified by testing the closer's response to normal door resistance in Mccormick. Force limit calibrated if triggering at normal door weight in Mccormick, SC.
Floor level and door path inspected for physical obstructions where sensor LEDs are both solid and limit settings are correct in Mccormick, SC. Spring balance assessed where force limit interaction is suspected in Mccormick. Opener component assessment where all physical causes have been ruled out in Mccormick, SC.
After repair, the door is closed fully to confirm correct contact with the floor seal in Mccormick, SC. The beam interruption test is performed by passing an object through the sensor beam during the close cycle to confirm the door reverses correctly in Mccormick. Both the correct close and the correct safety reversal are confirmed before EZ Open leaves in Mccormick, SC.
