Dryer will not heat, E05 displayed, cycle may continue with cool air only

Safety first: Disconnect power before removing any panels. Heating components and metal surfaces may be hot.

• Confirm symptom: Run a timed dry cycle on high heat and check if the drum air remains cool. If there is no heat and E05 appears, proceed.
• Locate inlet thermistor: The inlet thermistor is typically mounted near the heater housing or air inlet inside the drum bulkhead. Remove the front panel or drum as needed to access.
• Inspect wiring: Check the thermistor connector and wiring for loose pins, discoloration, or damage. Reseat the connector firmly.
• Test thermistor: Disconnect the thermistor and measure resistance at room temperature. Compare to Monogram specifications. Replace the thermistor if readings are open, shorted, or out of range.
• Check control connections: At the main control board, verify that the thermistor harness is fully seated and not pinched or damaged.
• Re-test: After replacing the thermistor, reassemble the dryer, restore power, and run a test cycle. If E05 persists, the main control board may be defective and should be evaluated by a technician.
