Refrigerator Control Board Replacement Cost
Erratic everything. Random warm ups, fans that start and stop, dead displays, compressor never running with a good relay, or a fridge that died in a storm. The main board runs compressor, fans, defrost, and dampers, but like all boards, it’s over diagnosed. Cheap sensors and relays mimic it constantly.

What causes it, and what each fix costs
Main control board failed
Surge damage and failed relays on the board are real, after thermistors, relay, and fans check out.
Display/dispenser board
Dead UI with a working fridge behind it.
Inverter board (variable speed compressors)
On inverter compressor boxes (most LG/Samsung, newer Whirlpool), a separate inverter drives the compressor and fails more often than the compressor it drives. Much cheaper than a compressor, verify which one it is.
Repair or replace?
Repair on anything premium or under ~8 years. The inverter-vs-compressor distinction matters enormously. A $300 inverter board saves fridges that were misdiagnosed as needing $900 compressors.

Scrap pickup for a machine that's finished, or a cash offer if it still has life in it. Working units, recent models and premium brands are often worth real money.
Quick Questions
The fridge died in a lightning storm, board?
Most likely, and it’s the best case scenario. Boards are the fixable version of surge death. A surge protector rated for refrigerators is worthwhile where storms are common.
