Why Replace Your Thermistors?
Failed or drifting thermistors are a common cause of error codes, improper defrost cycling, and system shutdowns in mini-split systems. Replacing a faulty thermistor set with the correct OEM part restores accurate temperature feedback to the control board, ensuring the system operates within designed parameters and protecting critical components like the compressor.
