Maytag Microwave Error Code E1

The E1 code on Maytag microwave models AMC5143AA* and MMC5193AA* means the sensor cooking cycle exceeded its maximum allowable time limit. The microwave uses a humidity sensor to detect steam and automatically set cook time, and E1 appears when that process runs beyond the built-in threshold. Pressing PAUSE/CANCEL and inspecting the food is the recommended first step.

Pressing PAUSE/CANCEL will cancel the current cycle and clear the E1 display. You can also unplug the microwave for a minute and plug it back in to fully reset the control board. However, if the underlying cause such as food conditions or a faulty sensor is not addressed, the error will likely return the next time sensor cooking is used.

If the error is caused by food conditions or a dirty sensor, there is no parts cost involved, just cleaning and adjusting how food is prepared for sensor cooking. If the humidity sensor itself has failed and needs replacement, repair costs typically range from around $75 to $200 depending on parts availability and whether a technician is hired for the repair.

Start by pressing PAUSE/CANCEL to clear the fault and check the condition of the food. If the food is undercooked, try reheating it using a manual time setting rather than sensor cooking mode. If E1 occurs repeatedly, clean the interior cavity to remove any residue that could affect the humidity sensor, and ensure food is properly covered and not frozen before using sensor cooking.

The E1 error is a control system fault rather than a safety hazard. The microwave stops operation when the time limit is exceeded, which actually prevents overcooking or overheating. The unit is safe to use in manual cooking mode while you investigate or resolve the sensor issue.
