Maytag Dryer Error Code i5

The i5 error code on a Maytag dryer indicates a heater temperature control problem. This means the control board has detected an issue within the heating system where temperatures are not being regulated correctly. The heating circuit in an electric dryer includes the heating element, high-limit thermostat, cycling thermostat, and thermal fuse, all of which work together to maintain safe and effective drying temperatures. When any of these components fail or send signals outside of expected parameters, the control board logs the i5 fault.

Common triggers for this code include a failed cycling thermostat that no longer opens and closes at the correct temperatures, a faulty high-limit thermostat that trips prematurely, or a heating element that has partially shorted. Restricted airflow from a clogged lint trap or blocked exhaust vent can also cause overheating conditions that stress the temperature control circuit and trigger this fault. In some cases, the control board itself may be misreading sensor signals due to internal component failure.

Because this error involves the heater and its associated safety components, Maytag's guidance is to call for professional service rather than attempt self-diagnosis. A qualified technician can test continuity across thermostats and the heating element, verify proper voltage delivery to the heater circuit, and inspect the exhaust path for blockages. Attempting repairs without proper tools and knowledge carries a safety risk, particularly given that the heating system operates at line voltage.
