Before you replace the entire Defrost Control Board though, be sure to individually test both the defrost heater and the defrost thermometer. You can check this out by turning the defrost cycle timer dial slowly to the defrost cycle. This should result in the compressor turning off and the heater turning on. If this does not happen it is most likely the proper time to replace it with a new defrost timer.
A Kenmore freezer cannot cool down if the compressor is broken because there is no movement of refrigerant throughout the unit. However, the refrigerant also may not draw and release heat if the coils are covered or the fans are broken. There could also be issues with the door seal or control board.
A Maytag fridge that is producing too much ice, indicates the ice bin is out of position. Or, there is something in the ice bin. If there is no ice production it’s generally an issue with the parts of the fridge that supply the water, or the ice maker is turned off.
As a general rule, it’s caused by insufficient water pressure, the water filter being restricted, or the water inlet valve being defective. The water filter is the easiest to inspect and repair or replace so it should be inspected first, followed by the water pressure and the water inlet valve.
The temperature can be turned down using the controls. Other than that, the vents may be blocked which stops the evaporator fan from pushing cold air into the fridge. The condenser coils can also be covered in dust or pet hair and cause them not to function correctly.
A Kenmore fridge will not work if heat from the fridge cannot be removed or if cold air cannot circulate freely through the compartments. Ice buildup, overfilling or dirty condenser coils can all be reversed, whereas a broken evaporator fan, condenser fan or compressor will need to be replaced.
Generally, the first thing you should do is check that it is turned on. Also, new fridge installs can take 24 hours for the ice maker to start working. After that, the water valve or the water filter can be the issue, and you need to ensure both aren’t damaged.
As a general rule, start by closing your fridge completely and waiting for 1 minute. After that, open the fridge again and see if the lights are working now. If that didn’t get the lights working again, then there can be an issue with the light switch, or the light bulbs can be loose or blown.
Generally speaking, if your ice maker is not producing ice, it is likely due to one of just a few problems. Most people will be able to fix the problem within a matter of minutes by thawing the unit and starting from scratch. There may also be some issues that are better left to the professionals.
