GE Monogram ZFSB26DNA installed 2002. Cools fine. When compressor goes off, makes a sound like ca-CLUNK-CLUNK. Been doing it years but getting on our nerves. Repairman says compressor is bad. Is it?

SOURCE: Refrigerator/freezer gets warm intermittently

sounds like your thermostat is faulty
the thermostat reads the temperature of the cabinet and controls the temperature
the 1 thing to check on the uprights is the evaporator is in the freezer and that makes the cool then there is a fan that blows the air around the fridge and freezer to freeze things
now there is a cycle that hapens to cycle usualy every 12 hours and that is the defrost cycle
this cycle turns off the compressor and fan turns on an defrost element on the evaporator and heats up the coils to get rid of the ice
the ice turns to water and runs through a drain to a evaporator tray and when the cycle is finished the fridge stars up again and goes into the cooling state again
when the thermostat decides that the fridge is cold enough it turns of the compressor and so on it goes through the cycles as required
if the drai is blocked or the defrost system is not working the evaporator will get choked with ice and the fan will not beable to let air through to cool things off

Carben,

I have the same problem and I am able to resolve it by defrosting the element which is behind the inside rear panel of the freezer. I use a hair dryer to melt the ice build up. It happbed a couple of times so I know that there is a cause for this which may be the defrost heater but I am not sure how to confirm this. Let me know if you have any ideas.

Did you clean the condenser?  Is the unit FULLY defrosted?   Defrost fully!!!!!!
Did he check the amount of gas in the unit?  If your unit has low gas...it is in need of more.  R12 is expensive.
Check gas level:  Shut unit for at least one hour.  View compressor.  Several pipes...we're looking at the largest.  Start the unit.  This pipe will begin to frost.  If it does not clear to dry, ice or wet...stays frosted...it is low.  Get the repair guy back ... but ask how much he'll charge first.

Sounds like a faulty thermostat. Try replacing it with a known good one and retest.

Possible faulty freezer fan motor. Dirty condenser. Faulty control board.
