The heater continuity is OK & the bi-metal too is OK. The temperature control knobs of the freezer and fridge are both set at NORMAL (in the center)

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: Refrigerator does not cool
If the refrigerator cooling is poor, it may be a problem with the thermostat, the compressor, or the evaporator fan. If ice is accumulating at the back of the fridge, that can also be a reason for poor cooling.

SOURCE: Hi, We have a whirlpool eb22dkxfw01
need to check for ice build up in air vent. if not make sure you hear your evap fan blowing in the freezer section. this blows your cold air into the fresh food side. do you have ice build up on rear wall of freezer section?
SOURCE: evaporator coil freezing, replaced main control
It is possible you have a defective fan motor in the condenser area or evaporator area. Sometimes when they become defective they will run for a while and just warm up and stop while the compressor continues to run. I learned that one on four costly returns to the home. The cost was to me not the customer. Thanks, Sea Breeze
It can either be found in the temperature control box in the refrigerator compartment, or located somewhere near the compressor. When you find it, look for a round cam on the side. Using a flat screwdriver, turn it until it clicks. With the fridge plugged in, the compressor should be off and the defrost heaters should be warming up. You should either hear the ice crackling and melting and see the water flow down the drain tube to the pan below the refrigerator. After about 45 minutes, the compressor should turn on. Hope this helps you.
