In these tests remember that air must pass over both coils to create a lower temperature. This is normally all that is necessary. Either a meter or a lamp plugged into the same receptacle will determine if it is hot. This has embarrassed many homeowners.
3-Pull the toe plate (front bottom at floor level) and check the condenser coil for lint and foreign matter stopping the air flow under the refrigerator. This fan must run for the unit to operate.
It may be necessary to pull the unit from the wall and remove the black (normally cardboard or plastic) panel by removing the either or 5/16 hex screws. Air must circulate over both of these coils for the unit to operate and cool. Remove the racks and the ice maker if applicable.
5-Is the back panel of the inside of the refrigerator or freezing compartment iced.baldeagletraders.4-Do the door seals really seal or are they broken or cracked.
The evaporator compartment is hidden by a back panel inside the refrigerator. If so free it and check that the fan operates. A replacement will be available at any refrigeration supply house for $15 or so. Often the sound you will hear is the fan that blows air across the condenser coil under the refrigerator. Pull the plug from the receptacle
and check it for scorch, brown burn marks, or rough arc on the connecting prongs. There may be frost on this back panel indicating a frozen evaporator coil. I normally get supplies at First Choice. At this point check the coils for obstructions.
The evaporator coil and fan (in a two compartment refrigerator) will be located in the rear of the freezer compartment. Feeling the compressor vibrate should enable one to determine if the compressor is running.
freely. One can normally hear the compressor and it will be warm to the touch. Air must circulate. If the fan is bad, replace it, defrost the coil and resume the operation of the unit. An intake vent at the bottom of the freezing compartment and a vent into the cooling compartment must be free to allow air circulation. This can be opened by removing the screws securing it. When the thermostat is lowered below the temperature present in the refrigerator the compressor should start and run until the temperature of the thermostat is satisfied.
If the condenser coil is under the refrigerator, there will be a small electric fan that pulls air across the coil when the compressor is running. Remove all food from side bearing manufacturers the freezer. Normally one is under the tray and two above. Is the evaporator coil frozen solid? Is the small circulating fan running? Often the circulating fan will be frozen in place with ice on the coil. An inexpensive meter for $10 or more is all that is needed. Air over the coil keeps the evaporator coil free of ice and circulates the cold air into the cooling compartment.
