continuously running refrigerator

11 posts in this topic

We have an older Hotpoint refrigerator model CTF17CBC and lately the motor runs continuously, except when its in the defrost mode.  Dial is set at level 3.  We cleaned the outside condenser coils of dust but no change. Took the panel off inside the refrigerator and looked at the evaporator coils but did not notice any ice build-up. Did not check the defrost thermostat since it looked like it was defrosting alright. Had the timer replaced a few months ago. Checked around the seals and could not find any major leaks or gaps opening, maybe a little moisture around the edges. Noticed some water dripping on the floor and traced it to a wet line (refrigerent line?) on the back of the refrigerator leading from condenser coils located on the bottom of refrigerator going up to the freezer area (evaporator coils?) Could this seem to cause the motor to run continuously?

what are the temps in the fridge and freezer? If below recommended temps, then you may have a bad thermostat. If above normal temps and there is no frost buildup, evap fan is running and damper is working properly, then you may have a sealed system issue.

I guess the condenser fan is running?Make sure refrigerator light is going off when you close door.Then take panel off in freezer make sure the evaporator has a frost pattern all the way up on the evaporator.Your finger should stick to all the coils from bottom to top indicating a proper seal system and know freon leak.Make sure that black fan blade on the evaporator is not stripped.Also what are the temperatures?

May be an inefficient compressor.  There was a GE compressor recall in the late 1980's that covered almost every GE and Hotpoint model, both top mount and side by sides.  Although I think this model precedes the recall.  Frost pattern should tell the tale.

The frost pattern might be ok and still a weak , worn out compressor might be at fault

 

A lot of fridges live past there time /prime and end up running all the time

 

everything man made wears out

 

make your frost pattern check , if it's good and the box is keeping food cold , it's just wearing out .

Freezer temperature was about 8 degrees and the refrigerator temp measured 36 degrees.  I will check the evaporator frost pattern asaic, and post findings.

Is 3 the normal setting? Will the fridge turn off if you in set it to a much warmer temp? If the ff is at 36 or below and the fridge still runs despite the increase in temp setting, replace thermostat.

Interestingly, when turning the cold setting knob to a lower number (from 3 to 1) the motor would not turn off! Only when turned to the off position did the motor shut down.
