LTC22350SS Fridge Evaporator Fan not working

Recommended Posts

LTC22350SS /00 Fridge Evaporator Fan not working. This is a upper freezer and lower fridge unit. So the fan in the freezer does not work and I replaced it with a new one. It still did not work. Also the light in the fridge does not work. After replacing the evaporator motor and it not working I noticed a reset button on the Main PCB board located on the back of the Fridge. I pushed the reset button and the evaporator fan came on and the light in the fridge came on. Everything was working fine again. That lasted for about 4 to 5 minutes and it tripped the reset on the PCB again. Every time I reset it it would run properly for about the same amount of time and stop working again. So I ordered a new PCB board and put it in and it is still doing the same thing. Any ideas on how to fix the problem?

Thanks for your help.

That is not a reset button. That button is used to put it into test mode. It is designed to come out of test mode at about 5 minutes.

If it is a test button why will it work fine for 4 of 5 minutes after I push it? Is there a test sequence I can run it through to find the problem? If the fan in the freezer and the light in the fridge will not work until that button is pushed somewhere along the line I have a problem.  I thought it would be in the control board but I must of been wrong.

Thank you for your help on this.

Nope you just proved fan works. 

 

Now you need to determine why the board isn't telling it to run. 

Either board borked or sensor not telling board it's warm in the unit and it needs to run.
