Mabe Refrigerator Error Code EH

The EH code on a Mabe refrigerator indicates a circuit fault in the ambient humidity sensor. This means the main control board is not receiving a proper signal from the sensor that monitors moisture levels in the surrounding environment. The issue can stem from a loose connector, a damaged wire, or a failed sensor or control board.

The EH fault relates to the humidity sensor circuit and does not directly disable cooling, so your food may remain cold in the short term. However, the control board relies on humidity data to optimize certain functions, so running the refrigerator in a fault state for an extended period is not recommended. Schedule a repair as soon as practical.

Repair costs vary depending on the failed component. If only a connector cleaning or reseating is needed, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the ambient humidity sensor generally adds $20 to $80 in parts, while a main control board replacement can range from $150 to $350 or more in parts alone, plus labor.

The first step is something most homeowners can safely attempt: locate the ambient humidity sensor terminal on the main control board, disconnect it, check for any debris or corrosion, and firmly reconnect it. If the error returns after that, further diagnosis of the sensor and wiring requires some technical knowledge, and board-level repairs should be handled by a qualified technician.

A power reset by unplugging the refrigerator for a few minutes may temporarily clear the EH code, but if the underlying circuit fault is still present, the code will return. A reset alone does not fix a faulty sensor, damaged wiring, or a loose connector. The root cause must be diagnosed and corrected for the error to stay cleared.
