Questions & Answers

For Frigidaire Defrost Timer (Part Number: OEM7778730)

1 Answer

WT, It is not uncommon for over a period of time for the ice to clump together. If it is happening every time then it sounds like the timer is sticking in the defrost for too long. There is not a shorter length of time for the timer.

Pedro for Model Number HMG-1862-4

I purchased a new defrost timer and it came with a jumper wire which the original one did not have. My refrigerator has four wires going to the connector. The instructions state for the three wire hook up to connect the jumper between terminals 3 & 4. Is the jumper required for my application? I hooked it up per the instructions and after running for a period of time it blew the circuit breaker?? I removed the jumper, the refrigerator seems to be operating fine, but the defrost timer seems to get to a point and not move any further. Should this timer run continuously, like a clock? Have I damaged the timer? Thanks for your help!!

Hello Pedro. Based on the information you provided, the timer does not need the jumper wire. Check and make sure the numbers on the new timer match up with the old timer numbers. If so, you may have damaged the timer 215846604 with the jumper wire. Hope this helps.

Hello Pedro. Usually the defrost timer is located in three places. Either in the control section, behind the toe panel, or on the back of the unit by the compressor. We can not get the model number to work as well. Look in these locations and see if it is there. Hope this helps.
