My Lg refrigerator is not cooling. The freezer works. I replaced the main circuit board due to the control panel on the inside not lighting up properly but it still is not cooling. Any suggestions?

Make sure the thermister is attached firmly to the fins in the back. The boards on a Norcold can be reset a service center familiar with this process is your best bet. It takes disconecting the board and then shorting it out best to leave it to some one who is familiar.

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.
