Maytag Dryer Error Code HP

The HP code means the thermistor, which is the dryer's temperature-sensing component, is producing a reading outside its normal operating range. The control board detects this abnormal signal and interrupts the drying cycle as a precaution. The fault can originate from the thermistor itself or from a problem in the wiring circuit connected to it. Entering the dryer's diagnostic mode and checking for sub-code 1 or 2 will help identify the specific nature of the fault.

The dryer interrupts the cycle when the HP code triggers, which means it is not operating normally and should not be used until the fault is diagnosed. Running a dryer with an unreliable temperature sensor creates a risk of improper heat regulation. It is best to resolve the thermistor fault before resuming normal use.

If only the wiring connection needs to be reseated or cleaned, the repair may cost little to nothing beyond your time. Replacing the thermistor itself is a relatively inexpensive fix, with parts typically ranging from $15 to $40 and professional labor adding $75 to $150 depending on the service provider. If the control board is the root cause, costs increase significantly, generally ranging from $150 to $350 or more for parts and labor combined.

Pressing the Off key and restarting the cycle is the recommended first step and may clear the code if the thermistor reading was temporarily out of range. However, if the underlying fault, such as a failed thermistor or a loose wiring connection, is still present, the HP code will return. A reset is useful for ruling out a transient glitch but is not a permanent fix when a hardware problem exists.

Start by entering the diagnostic mode and noting whether sub-code 1 or sub-code 2 appears, as this provides direction on the type of fault. From there, inspect the wiring harness and connectors for visible damage, corrosion, or loose connections. If the wiring looks intact, use a multimeter to measure the thermistor's resistance and verify it falls within the expected range for the operating temperature.
