Questions & Answers

For Frigidaire Refrigerator Defrost Timer (Part Number: OEM7778730)

1 Answer

Sam, This issue does not sound like it would be a defrost issue. This would most likely be caused by a drain clog in which you would want to get the drain kit part number W10619951 and install it on your unit. This would help to correct the clogging issue.

William for Model Number frt18g6jw6

I've had problems with my fridge. The freezer works perfectly, but the fridge isn't cooling. I found out the heater wasn't working, so it was freezing up the air duct to the fridge. I have since purchased these parts from your company. FRIGIDAIRE Defrost timer (215846604) FRIGIDAIRE Defrost thermostat (5303918202) FRIGIDAIRE Defrost heater (242044020) I have replaced them all, and it will work great for 2 weeks, then I have to open up the freezer and defrost it completely. It seems I'm not getting any power to the heater when the fridge is in defrost mode. I'm at a loss what the problem could be. I would greatly appreciate any insight to what else could be causing this problem. Thank you for your time. William

William, You will want to take the control housing down in the refrigerator compartment and set the timer to defrost. Test from the light blue wire to the brown wire for 120 vac. If there is voltage then you would want to test at the heater to see if there is 120 vac. If there is power at the defrost timer but not at the heater then test the defrost thermostat for continuity and if there is continuity then this will be faulty wiring.

Selwyn for Model Number fght1834KW2

Freezer freezers and defrosts on and off - much too often - so before hard solid ice gets to form, it turns back into water. Could this be a faulty defrost timer? Can I reset it before I buy a new one? If so, can I do it through the access hole in the cover? I can see the round grey dial with a mirror. Would I need a special screw driver to turn it? It looks like the slots are beveled so the knob can only be turned clockwise. Please send instructions if applicable. Thank you, Selwyn

1 Answer

Selwyn, The defrost timer can be turned using a flat blade screwdriver but it cannot be reset and would need to replace the timer.

Hello John. You will need to see if the unit is stuck in the defrost cycle. If so, then the timer 215846604 is bad and will need to be replaced on the unit. Also, check the cold control 241537103 to see if it is bad on the unit.
