Why is water leaking from the bottom of the evaporator in my Follett T400A?
If water is leaking from the bottom of the evaporator in your Follett Ice Maker, it's likely due to a broken O-ring seal, which will need to be replaced.
Why my Follett T400A unit runs but is not making ice: compressor, gearmotor and fan motor running?
If your Follett Ice Maker is running, but not producing ice, while the compressor, gearmotor, and fan motor are all active, the condenser coil might be clogged or dirty, requiring cleaning. Another potential cause is a compressor that isn't pumping, which would necessitate replacement. Additionally, a low refrigerant charge could be the issue; check for leaks, repair them, evacuate the system, and recharge it to the correct level.
Why is my Follett T400A Ice Maker compressor cycling intermittently while the gearmotor and fan motor run?
If the compressor in your Follett Ice Maker cycles intermittently while the gearmotor and fan motor continue to run, the compressor start relay may be in the wrong position; ensure the relay is positioned with the arrow or the word 'top' facing up. Another cause could be a high-pressure cutout open due to high head pressure; check the supply and temperature of water to the water-cooled condenser. Additionally, a clogged or dirty condenser coil could be the problem; clean the condenser coil. A defective compressor may also be the cause, requiring replacement.
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.
Why is my Follett Ice Maker compressor not running but gearmotor and fan motor run?
If the compressor in your Follett Ice Maker isn't running, but the gearmotor and fan motor are working, the condenser coil might be plugged, causing an open overload or high-pressure cut-out; clean the condenser coil and replace the overload if needed. Other possible reasons include a defective starting capacitor (replace it), a defective starting relay (replace the relay), or an open motor winding (check winding resistance and replace the compressor if necessary). Also, check for no power output from the compressor output terminal on the control board; inspect the terminal connection and replace the control board if required.
What to do if my Follett Ice Maker runs for a short period and shuts down on torque error?
If your Follett Ice Maker runs briefly and then shuts down due to a torque error (20M or 2nd LED lit), first check for a kink in the ice transport tube and ensure it complies with the installation manual. Also, see if the bin level control remains in a closed position, and adjust or replace it if needed. Other potential causes include a ruptured ice transport tube (replace the entire tube), worn evaporator bearings (inspect and replace if necessary), or a faulty gearmotor start relay (replace the relay). Lastly, make sure ice contacts the bin thermostat before backing up in the transport tube.
Why my Follett Ice Maker will not run: compressor, gearmotor, and fan motor inoperative?
If your Follett Ice Maker isn't running and the compressor, gearmotor, and fan motor are inoperative, start by checking the power supply: ensure the unit is plugged in and the circuit breakers are on. An open bin level control could also be the cause; try adjusting or replacing the ice level control. If the Water OK LED (WTR) isn't lit, check the reservoir for water and restore water to the unit. Also, check if the 20M or 2ND LED is on, indicating a torque error. Other potential issues include a locked-up gearmotor (repair or replace the gear motor) or an open coil on the gearmotor start relay (replace the gearmotor start relay).
How to troubleshoot low ice production and poor ice quality in my Follett T400A Ice Maker?
If your Follett Ice Maker is showing low ice production or producing poor quality ice, there are several potential causes. The air filter or condenser coil might be dirty, needing cleaning or replacement. There could be restricted airflow to the condenser coil, requiring removal of any obstructions. The evaporator might be coated with minerals, necessitating cleaning. Other possible causes include a faulty expansion valve (requiring replacement), a low refrigerant charge (check for leaks, repair, evacuate, and recharge), or an inefficient compressor (requiring replacement). Also ensure the TXV sensing bulb is securely clamped and insulated, and that proper exhaust air provisions are in place.
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 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.
