My refrigerator twice now hase shut down. The freezer still works, and actually frosts over any ideas how to

Question

how to fix it. We defrosted it last time and that worked, is that just somthing that needs to be done every so often or could this be a more sreious problem

Answer 1

If you have the knowledge and a meter here it goes, the box has a defrost system that will melt the ice off the coil, it has three parts.  One the defrost heater, two the defrost thermostat, three the defrost timer. The timer is a clock that about every eight hours turns off the cooling and turns on the heater, the defrost thermostat opens and turns off the heater around 45-50 degrees. This defrost cycle last about 20-30 minutes and then the timer will turn the cooling back on. So if you turn the timer and the heater works then the timer is sticking. If the heater does not come on than the heater or t-stat is open, bad.

Answer 2

get a new fridge

Answer 3

If the freezer frosts too often(more than once a year), then its door seal is leaking.Unless it is self defrosting then you have bigger problems

Answer 4

i have had the same problem to my frig and know of others. in all those cases it was the heating coil that's inside your freezer that normally comes on and off a few times a day so you have no frost in it. anyway the coil is staying on and since your freezer wants to be cold will run and run freezing the fan to the frig that's why it doesn't work but also is the reason your having frost buildup in the freezer. id call a repair person to look into it.

Answer 5

try pulling it away from the wall, & vacuum the back side out. dust & dirt tend to clog up back there. also clean bottom part near the floor back there, coils that are dirty will do what you described.

good luck.

Answer 6

There should be a channel in inside the fridge in the back.  There is a fan that pulls cold air from the freezer down into the refrigerator portion.  This is part of the defrosting mechanism in the freezer.  If this ices up, the cold air no longer gets into the refrigerator portion AND the freezer ices up.  Pull everything out of the fridge and examine this. It may well be contributing to your problem. A few screws should pull the cover off this channel. Next time, look for an ice dam.
