I have been having defrost issues for several months on my Frigidaire. It started after a burning smell that seemed to be coming from the fridge. I have replaced the Temp Control Board because that went out. I changed the Defrost Therm. The defrost heater is reading 30ohms so I decided to change the main board thinking that would solve the problem. Well, it didn't. Does anyone have any other suggestions?

It is no defrosting. I tried to turn on the manual defrost but that also does not work. The fresh food side of the fridge was warm and that is how I noticed the evaporator coils were frosted over. I manually have been defrost coils with a heat gun but that is getting old. The only part left to change is the defrost heater itself but based on the continuity test heater should be good.

I would check the continuity of the defrost system.
Make sure that the defrost thermostat, evaporator coil is frozen.
Unplug the unit.
Measure from J1-11 at the defrost board (Neutral) to J1-7 (heater/thermostat combo).
It should read about 30 ohms.
This then checks all components including the wiring in the defrost circuit. |

At the top of my list would be a bad defrost board. |

I had the defrost issue before I replaced the temp control board. The temp control board is new. I then changed the main control board and it is still not defrosting. What is the part # for the defrost board?

Sorry but I did not look up the info on this unit before answering. Since you said defrost I just used that term but there is not a separate defrost board in this unit. The correct board is Part number: AP5645865
