ApplianceMicrowave
Spotted C22 on a Samsung microwave? Samsung’s table reads it as a temperature sensor error. The neighbours C-21 and C-20 are worded identically. The listing applies to the present generation of Samsung microwaves.
Power-cycle checklist
Remove power first, using the outlet or the circuit breaker.
Let the microwave dry if it met a spill or steam from the cooktop.
No moisture at all: hold off for 60 seconds, then plug in or flip the breaker back on.
When the code returns, requesting service is what Samsung advises.
