If a Miller mobile home furnace only runs for a few minutes then shuts off, check to see whether the flame sensor is defective, and replace it if necessary. Inspect the draft inducer and the pressure switch. A malfunctioning draft inducer motor may fail to shut off the pressure switch, causing the ignition process to stop. Check these parts for continuity, and replace any of them if defective. If the problem persists, check whether the furnace air inlet is blocked, and clean it out if necessary.

If the furnace does not heat, check to make sure that the device is plugged into a working electrical outlet. Replace any blown fuses, and reset tripped circuit breakers. Confirm that the thermostat is set to heat and turned up. If this does not solve the issue, examine the control board, and replace it if faulty.

If a Miller mobile home furnace is noisy, inspect the blower wheel and the fan motor, and replace any of the parts if damaged. If these repair methods do not remedy the issue, contact a Miller professional for assistance.
