How much does it typically cost to repair an E1 22 error on a Samsung AC?

The cost varies depending on the cause. Replacing the temperature sensor itself usually costs between $50-$150 for the part, plus $75-$200 for labor. If the issue is wiring, the cost might be lower. However, if the error has caused damage to other components (like the compressor), the repair cost could be significantly higher, potentially $300-$800 or more.
