Question about GE PTS22LHR Top Freezer Refrigerator

1 Answer

Evaporator fan not working

GE PTS22LHR, 2004 model, compressor and condenser fan are working, but evaporator fan is not. I downloaded the service manual (published in 2001) only to find out the main board in the refrigerator is nothing like the one in the maual, nor like these website's replacement part. There is no ICs or SMT parts but only relays, chokes and connectors on my current main board, but the connector designations and wire color code matched service manual, any one knows what is going on?

Both freezer and fresh food compartment are 10-20F higher than the set temperature.

    Is the part in the following picture you refered? Each grid is 1" in the pic. I thought the same thing as you did at begining. But when I opened the back cover in the freezer, there is no frost build up. defrost is working. The problem is that the main board I have does not have parts (i.e. microprocessor, capacitors, diodes, etc.) needed to control this refrigerator. I even called GE to find out whether they change the design, they were clueless (Duh, the board has Sanyo name on it). The only assumption I have is that they moved secondary (low voltage DC components) control to the temp. control board which is located in the front between the freezer and the fresh food compartment. An updated service manual (post 2001) would be very helful.

Most G.E. the fan will not work if limit control is not working, staying in open position.This also means the defrost heater will not work. If you had an amp probe it would simplify your diagnoses. you could put it into defrost,and if the amps showed heater was not coming on it would prove my theory. The limit control is a small button like switch about 1 inch in diameter cliped to the cooling
coils in back of freezer. Hope this helps.

The reason everything is hot is because you stopped the unit from "Breathing" through the condenser (not evaporator) by allowing dust to build up.
This is how the system disperses heat absorbed in the freezer section (evaporator).

Unit not cooling down,compressor running,condenser fan running. suction line just cool,condenser line barely warm.


Check if evaporator fan is running. Is there any frost buildup on freezers evaporator cover? If so you have a defrost problem (bad heater, defrost thermostat, thermister, defrost timer or circuit board ). If no frost and the freezer is warm then you most likely have a sealed system problem(leak, restriction, bad compressor) which is costly to repair.

Dirty condenser, condenser fan or evaporator fan motor are not running, Ice build up on evaporator and restricted the air flow. If compressor, condenser fan and evaporator fan motor are running but not cooling, then either compressor or sealed system problem.

Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

Only the fan at the compressor turns on and off with the compressor cycle. The evaporator fan runs steady to maintain air circulation and temperature balance and to affect evaporator defrost in the off cycle. Sometimes the condenser fan will run continuously to assist in the evaporation of condensed moisture from the evaporator drainage.

Evaporator fan not working


have you check the thermostat as follows ?
:
1. operation.
2. circuit from thermo switch (stat) to relay and the function of the relay, the stat should close and coild on relay should be powered, thus closing contacts to pull in evap fan.
assume you are carefull enough not to electrocute yourself in the process, short out relay contacts to see if fan runs. if it does and stat actually is okay. replace relay on board it may be faulty or may have anboard maufacturing fault such as dry solder joint etc.
alternatively if you have a good friend good al electrical work have him relace relay for you.

as an emergency fix , connect evap fan to supply, thus by passing control bard al togheter, ths should give you you 10 degress straight away and keep you rubnning till you solve board level problem.
