Amana Refrigerator Not Defrosting, Model BBI BC2 BRF SBD SBI SRD Series. Clients often contact us when their Amana refrigerator is warm and not defrosting. This is a common defrost control failure that FixYourBoard.com repairs. Even more often, we get inquiries regarding defrost issues and how to determine if the controller is at fault.  Luckily, this is a fairly simple task because there is a test feature built in to the models listed at the end of this post. This test procedure is called “Force Defrost”. This might sound a bit wild, but in a nutshell, if you open and close the door 4 times within 8 seconds the electronic controller will go into forced defrost verifying its functionality.

If you have an Amana/Maytag refrigerator series BBI BC2 BRF SBD SBI or SRD, you may be experiencing some of the following problems due to a worn out adaptive defrost control board.

• Freezing/Ice Build-Up
• Not Maintaining Cold Temperature
• Warm Freezer
• Compressor not Running

These models will have one of the following electronic defrost control part numbers– 12050501,

12050504, 12050505, 10678002, 12050506, or 10461504

There is a simple troubleshooting technique to test the defrost and compressor control.  Below is from the Amana documentation:

Forced Defrost

• To force a defrost cycle, open and close either the freezer or refrigerator door light switch 4 times in a 8 second period. Allow atleast 1/2 second between each switch condition.

Important

1. The compressor must be operating when forcing defrost.
2. The evaporator fan motor is fan delayed through the defrost thermostat and will not function after a defrost cycle until the defrost thermostat closes.
3. To bypass the 6 minute dwell time after a defrost or to terminate a forced defrost, disconnect power to the refrigerator for 30 seconds.

Input Voltage Readings and Checks

L1 to L2 – line voltage should be present w henever the refrigerator is powered.
K to L2 – line voltage should be present w ith cold control contacts closed.
T to L2 – line voltage should be present w hen cold control contacts are closed, defrost terminator is closed,
and adaptive defrost control is in defrost mode.
R to L2 – line voltage should be present w ith refrigerator door open (door light sw itch closed).
F to L2 – line voltage should be present w ith freezer door open (door light sw itch closed).
Outputs Voltage Readings and Checks
C to L2 – line voltage present w hen in refrigeration mode w ith cold control contacts closed.
