Mabe Refrigerator Error Code E1

The E1 code on a Mabe refrigerator indicates a temperature sensor fault in the refrigerating chamber. The control board is not receiving a valid signal from the thermistor that monitors the fresh food compartment temperature. This can result from a loose connection, a failed sensor, damaged wiring, or in rare cases a faulty control board.

A power reset may temporarily clear the E1 code, but the error will return if the underlying cause is not addressed. If the fault is due to a loose terminal, reseating the connector before resetting may resolve it permanently. If the sensor or wiring is actually damaged, a reset alone will not fix the problem.

If the issue is only a loose connector, there may be no parts cost at all, just the cost of a service call if you hire a technician. Replacing the temperature sensor typically costs in the range of $20 to $80 for the part, plus labor. If the main control board needs replacement, costs can range from $100 to $300 or more depending on the specific model and labor rates in your area.

Start by locating the temperature sensor terminal on the main control board, disconnecting it, and firmly reconnecting it to ensure a solid electrical connection. If the error returns after reconnecting, inspect the wiring harness for damage and test the sensor itself. A faulty thermistor will need to be replaced to clear the fault permanently.

Operating the refrigerator with an active E1 error is not recommended for extended periods. Because the control board cannot accurately read the compartment temperature, it may not regulate cooling correctly, which could lead to food stored in the fresh food section being held at unsafe temperatures.
