Jenn-Air Microwave Error Code ERROR

The ERROR code on a Jenn-Air microwave indicates that the absolute humidity sensor has been detected as disconnected during sensor cooking mode. The microwave uses this sensor to monitor steam levels and automatically determine doneness. Because the bridge circuit that processes the sensor signal cannot balance without a connected sensor, the unit faults out. This error will only appear when using the automatic sensor cooking functions.

Manual cooking modes that do not rely on the humidity sensor may still function while this fault is present. However, sensor cooking modes will not operate correctly without a functioning sensor connection, and using the microwave in that state could result in improperly cooked food. It is best to resolve the error before relying on the appliance for sensor-based cooking.

Repair costs depend on the cause. If the fix is simply reseating a loose connector, there may be no parts cost, though a service call from a technician could run anywhere from $75 to $150 or more depending on your area. If the absolute humidity sensor needs replacement, parts typically range from $30 to $100, plus labor. A control PCB replacement is the most expensive scenario, with parts often ranging from $100 to $250 or higher before labor costs.

In many cases, yes. The first step is to check the humidity sensor cable connection at connector CNF on the control PCB and confirm the black, red, and white wires are intact and the connector is fully seated. If a loose connection or damaged wire is found, reseating or repairing it may resolve the error. However, if the sensor itself or the control PCB has failed, those components would need to be replaced, which may require a technician depending on your comfort level working inside the appliance.

A power reset may temporarily clear the error code display, but the fault will return as soon as sensor cooking mode is activated again if the underlying disconnection is not corrected. The root cause, whether a loose connector, damaged wire, or failed sensor, must be addressed to permanently resolve the code.
