It is possible that the defrost cycle is not working. Look for signs of ice built up in the freezer compartment. The excess ice prohibits the air circulation.
If defrost cycle appears working and compressor runs continuously it is probable that the Freon is low or compressor is failing.
the usual tell is the refrigerator gets colder than usual and the freezer does not get as cold. The situation is that the compressor runs until the freezer temperature is satisfied. If the compressor can not achieve the cold temperature of the freezer it will run continuously.
When the unit runs continuously the bi-pass of air is increased bringing more cold air into the refrigerator portion of the unit.
check the condensor fan in the compressor area and make sure its running if not the compressor will overheat causing high head pressures on the compressor causing it to draw too much current to operate the compressor and kick the breaker out,also make sure the condenser coils there are clean and it has ample air movement away from the wall
When your unit thaws - do you hear the compressor kicking on at the start of a cycle? If not, maybe the compressor relay it hanging up somehow. Or the compessor capacitor is malfunctioning. It is NOT a compressor problem though.
If you are capable of getting to the defrost heater circuit, you should check the defrost thermostat and timer (if there is not ice build up behind the panel. If the defrost circuit is active too long it could cause that condition - but you defrost heater is not the problem unless there is an ice build up.
Sounds like the defrost circuit of your fridge has failed. If you remove the back panel of the freezer compartment, you will see the evap coil encased with ice. Normally the defrost circuit will turn off the compressor and turn on a heater to warm the coil to about 45 degrees to melt any frost build up. After about 40 minutes the compressor will kick back in to keep your fridge cool again.
The typical failures are that the defrost heater burns out. If you have an older fridge, the defrost timer fails to advance, causing the fridge to stay in cooling or defrost mode.
Hi,the problem is from the relay switch attached to the compressor which supplies power to the compressor,it's probably weak or bad,
The solution is to replace the relay switch with another new one,and your problem will be solved.
Sounds like the overload/relay plugged onto the compressor is bad . Easily replaceable . Pt # 12002782 . Remove the back panel and disconnect from electrical outlet . On the compressor itself , this piece had 3 wires going to it .
You may be low on R134a and need a simple charge. As the Compressor cycles, the low side pressure drops and if it drops to far it will cut the compressor off till the pressure rises again. The high pressure side rises and the low side drops, but when it drops to far since there is not enough R134a in the system you get the on off cycle. The other cause to this is a bad pressure switch, or bad expansion valve, and moisture in the system as it ices up in the lines and pressure builds causing the pressure switch to cut the compressor off too. Re-cap, try recharging the a/c system for now since it's still working. Good luck and keep me posted. Be glad to help.
The clicking sound is either from your fan clicking against ice that's built up or from your compressor trying to kick on. Unplug your fridge and let it defrost for a day with the doors open. You will want to put everything in a cooler with plenty of ice. The next day plug your fridge back in. This should solve the click if it's your fan. If it doesn't then the click is in the compressor and you will need to hard start it. Hard starting a fridge is the equivalant of jumpstarting a car. It requires a specific machine. What happened was at the moment your compressor was going to kick on the power failed and so the compressor is frozen. Not temperature wise but figuratively. It needs a boost to get it kicking again. If you don't have a hard start machine consult fixya's local directory. This should just be a minimum service charge. I would try unplugging the fridge for a day first. It's cheaper. I hope this helps.
