SOURCE: Freezer/refrigerator compressor running constantly

th ebi-metal is a thermostat which shuts the defrost heater on/off, but doesnt actually put the unit into defrost. if it were bad the defrost heater would never go on resulting in massive build up of ice on back wall of freezer, and noticable refrigeration sect. cooling.. dont know how you know the compressor never shuts down, but if that the case perhaps you have a sealed system/ freon issue. try removing the back panel of freezer section and check the evaporator coil. you shuld have an even frost pattern over the entire evap coil. if theres just frost over the top 1or 2 coils, and the rest of coil is shiny aluminum , thats an indication of a sealed system issue.( 5 year part warr by manufacture) def not a do it yourself issue...but that would,, depending on extent of restriction/loss of freon,, cause freezer to freeze and defrost eratically,and the compressor would be running constantly trying to achieve a good stable temp

SOURCE: Freezer and refrigerator run but is not cold

Remove the back panel at the bottom. The refrigeration system is a sealed system and the smell would not come from it internally. Check and make sure the fan motor is running. If the fan motor (was) shorted out it would account for the reseting of the breaker. After resetting the breaker a number of times would cause the circuit in the fan motor to open allowing the compressor to run. Is the small line coming out of the compressor hot? If so replacing the defective fan motor may correct your problem.

SOURCE: the refrigerator is not cold inside.

Do you have an error code? More than likely you have a ER FF or 6,7. The problem is you have a build up of ice that is blocking your fan. The noise was the fan hitting the ice and the ice has no blocked it completely. Defrost your unit and remove the back panel on the freezer wall. Cut off a bit of the insulation as in the picture and you should be ok. The problem will not happen again if you do this.

SOURCE: Appears to be stuck in auto defrost mode

Your relay that is attached to the compressor is going bad. It is called a PTC relay. The clicking sound is a relay called PTC relay. You need to replace it. First be sure to unplug frig. Remove the cardboard cover that covers most backs of the frig units. Remove the plastic cover that is on the side of compressor. It is held on with a metal clip. Now you should be able to see the relay pry the relay straight off. note the wiring and position of relay. Only three prongs on compressor. Go to a parts house for appliance's and with your make and model number should be able to get a new one. Let me know if you need any more help. ken

Your PTC relay is bad and needs to be replaced. It is on the side of the compressor that connects the wires to it. Cost is about 50 maytag price or you could go with a 3 in 1 cost about 15. If you need any help get back with me and can walk you though it. Ken

Hi,

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions:

  • Is the refrigerator completely dead? If so, see “It's stopped completely.”


  • Is the thermostat knob turned to the proper setting? If not, reset it.


Next, see if the compressor motor is running

The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.

If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

  • The compressor


  • The Thermostat


  • The overload, relay, or capacitor


  • The defrost timer


  • The condenser fan motor

    When we got up this morning no power light and no sound. Outlet is good , where do we start?


    Hello Phil
    No Signs of Power
    If you did not find any signs of power before unplugging the appliance - no light, no motor, no fan sounds, the first thing to determine is whether your electrical outlet may be malfunctioning. Plug a lamp into the outlet to see if it has power. If the lamp works, then the problem lies with the refrigerator. If the lamp doesn't work, then you may have a blown fuse or circuit breaker.
    If the refrigerator is getting power but won't work, you may have a wiring, compressor, thermostat or overloaded relay issue. Unless you have specific appliance-repair skills, you may need to call in an expert.
    Insufficient Cooling
    If you've suddenly noticed that your food in the refrigerator doesn't seem as cold as it should, check a few things to figure out the problem. Check the thermostat setting to make sure that it's set properly. If the light is on but you don't hear the fan or the motor running, it's possible that the compressor isn't functioning. The problem could also lie with the thermostat, the defrost timer or the condenser fan.
    Take a look at the evaporator coils located in a panel in the freezer section of the appliance. If you find excessive frost built up over the coils, you may have a problem with the defrost timer. To fix this, you may need to turn the unit off to defrost the coils completely before the refrigerator will be able to cool properly again.
    Strange Sounds
    If you hear strange sounds, determine where they're originating. If the sounds are coming from the freezer, this could indicate an evaporator fan that's needing lubrication or replacement. If the sounds are coming from the outside back of the refrigerator, you may be dealing with the compressor, the condenser fan or the defrost timer. These parts often wear out and need replacing. If the noise is coming from the bottom of the unit, this may be a simple issue - your drain pan may be shifting. You can duct-tape the pan in place to stop the rattling.

    Defrosted it and now when plugged in, not getting cold.


    If the compressor is running then it ought to cool. If not shut if down once again wait for few hours and keeping the thermostat in the normal position switch on.
    If there is no cooling check if the compressor is working, If the motor speed seems dull check for capacitor being weak, gas pressure being down.
    Though it seems strange that a defrosted fridge does not cool and we must suspect the compressor..

    Refrigerator excess energy usage


    can't auto defrost. pls check your thermostat sensor for temperature inside the refregerator if working properly. thermostat function is to cutt off the compressor for running because thermostat reaches the cool settings.

    A c unit goes into defrost too soon then it will possibly go out of defrost and hiss loudly current draw rises over 20 amps trips breaker model is a L G L 12463hl 7 k w wall split


    It sounds like the head pressure is to high. This is sometimes do to overcharging. The hissing noise that you hear is the liquid refrigerant dumping into the suction side. This is what a compressor does when the Head pressure is way too high. The fact that it is tripping the breaker may be to a broken suction valve in the compressor. I think it might be time for a new unit.
