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

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 Polo. 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 Polo, IL. The diagnostic hierarchy exists because it works from the most common and least expensive causes to the least common and most expensive in Polo. EZ Open follows it in order because it produces the correct diagnosis at the minimum necessary cost in Polo, IL.
A garage door that won't close removes the physical security barrier between the exterior and the garage in Polo, IL. The garage is one of the most common residential entry points for break-ins in Polo. An open garage eliminates the locked door barrier that a closed and secured garage door provides in Polo, IL. Everything in the garage is immediately accessible in Polo. In homes where the garage connects to the interior through a door, an open garage provides effective access to the home in Polo, IL. 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 Polo.
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 Polo.

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