Side by side fridge won't defrost

I keep having to manually defrost the coil in the freezer cause it won't defrost. It takes a couple of months to get where the fridge starts warming up, then I open up the back of the freezer and use a heat gun to melt out all of the frost. So what is not working to make it not defrost? Thanks.

Two things to check, defrost heater, defrost limit switch, if ok, install new adaptive defrost control.

  • the limit switch is in the freezer part, behind back panel on top of evap. coil. must use ohmmeter and freezer needs to have ice on it. should ohm out infinity to be good. in other words, the limit switch should be closed at 20-25 degrees. the heater is a calgon solid rod with two wires, one at each end. always disconnect one end to ohm out each component.also best to turn off ref.

The defrost circuit is not working, there are usually 3 things that normally go bad, defrost timer, defrost heater, and thermal switch. Would have serviceman check it out as cooling fins on coils will cut you like a razor.

yes, dust build-up will cause over-heating and burn-out the defroster will need to have serviced to see which control board failed for sure. Keep those vents clear....every couple of months vacuum them.

Freezer and drain freezing up

you either have a blocked drain in the freezer or a bad, failing defrost element, timer.

If you have a manual for you fridge you can locate the place to check for blockage in the drainline. I you dont have a manual you can check online at searspartdirect and locate one.

The heating element for the defroster is located right beneath the freezer coils so you need to take the inner panels off the inside of the freezer to get to those.

You can replace the heating element and timer fairly easily. You should be able to buy both of them for around 90-100 bucks if necessary. But try clearing the draining first. You can test the line by defrosting the fridge and pouring some water into the drain and see how quickly it goes into the drainpan below the fridge.

Good luck and be careful.
