What causes intermittent noises from the evaporator of my Follett T400A Ice Maker?
Intermittent noises from the evaporator in your Follett Ice Maker are likely caused by mineral build-up on the evaporator surface. Clean the evaporator with a liquid ice machine cleaner to resolve this issue.
Why is my Follett T400A Ice Maker not making ice?
If your Follett Ice Maker isn't producing ice, several factors could be the cause. It might be due to a clogged or dirty air filter or condenser coil, which requires cleaning or replacement. The compressor may not be pumping efficiently, necessitating a replacement. Also, a low refrigerant charge could be the culprit, indicating a need to check for leaks, repair them, evacuate the system, and recharge it with the correct amount of refrigerant.
What to do if my Follett T400A Ice Maker has low ice production and poor quality ice?
If your Follett Ice Maker is producing low quality ice, several factors could be responsible. Begin by cleaning the condenser coil and removing any obstructions restricting airflow. A mineral-coated evaporator can also cause this issue, so ensure it's cleaned. High ambient water supply or air temperature may be the cause; precool the water or install an air duct. Other potential causes include improper exhaust air provisions, a faulty expansion valve, or a low refrigerant charge, which would require checking for leaks and recharging. Also, verify the superheat is correct by checking the TEV sensing bulb and its cover. Finally, an inefficient compressor could be the culprit, necessitating replacement.
Why is the evaporator on my Follett T400A iced up on the outside with no ice production?
If the evaporator of your Follett Ice Maker is iced up on the outside and there's no ice production, even though the compressor, gearmotor, and fan motor are running, the gearmotor might be running without any output rotation; check for a broken gearmotor output shaft or a damaged gearbox. Another possibility is an empty float reservoir; check for a defective water sensor (if the Water OK (WTR) LED remains on even when the float is empty or the probe is removed from the water). An air bubble in the water supply line could also be the issue, preventing water from reaching the evaporator; purge the air from the line.
What to do if my Follett T400A compressor will not run?
If the compressor on your Follett Ice Maker isn't running, several issues could be the cause. The condenser coil might be plugged, leading to an open overload or high-pressure cut-out, so you should clean the condenser coil and replace the overload if needed. A defective starting capacitor or relay could also be the problem, requiring their replacement. Additionally, an open motor winding could be the cause, so ohm out the windings and replace the compressor if necessary. Finally, there might be no power output from the compressor output terminal on the control board, in which case you should check the terminal connection and replace the control board if necessary.
Why won't the compressor and fan motor run on my Follett Ice Maker, but the gearmotor does?
If the compressor and fan motor on your Follett Ice Maker aren't running while the gearmotor is, first check if the compressor switch is in the OFF position and turn it ON. If that's not the issue, there may be no output on the compressor and fan motor terminals on the control board, in which case, replace the control board. A failed fan motor could also cause the high-pressure cut-out to open, so replace the fan motor.
Why is the evaporator iced up on the outside of my Follett T400A, and there is no ice production?
If the evaporator on your Follett Ice Maker is iced up externally and there's no ice production, investigate these possible causes: The gearmotor may be running without output rotation, indicating a broken output shaft or damaged gearbox. The float reservoir might be empty; check for a defective water sensor, noting if the Water OK (WTR) LED remains on even when the float is empty or the probe is removed from water. An air bubble in the water supply line could also be the problem; purge the air from the line.
Why does my Follett Ice Maker compressor cycle intermittently?
If the compressor in your Follett Ice Maker is cycling intermittently, several issues could be the cause. Ensure the compressor start relay is correctly positioned with the arrow or the word 'top' oriented properly. High pressure cutout may be open due to high head pressure, so check the discharge pressure and adjust the water regulator valve. A clogged or dirty air filter or condenser coil can also cause this issue, requiring cleaning or replacement. Improper ventilation could also be the problem. Finally, the compressor itself might be defective, necessitating replacement.
Why my Follett T400A compressor and fan motor will not run, but the gearmotor runs?
If the compressor and fan motor on your Follett Ice Maker aren't running, but the gearmotor is active, first check if the compressor switch is in the OFF position and turn it ON. If that's not the issue, there might be no output on the compressor and fan motor terminals on the control board, which would require replacing the control board. A failed fan motor could also cause the high-pressure cut-out to open; in this case, replace the fan motor.
Why my Follett T400A cycles intermittently: compressor, gear motor, and fan motor cycle?
If your Follett Ice Maker cycles intermittently with the compressor, gear motor, and fan motor cycling, it could be due to the float reservoir running dry. This causes the sensing probe to signal the system to shut down. Check the water supply to the float and the float operation itself. The PC board will likely have a flashing WTR LED.
