When your Goodman HVAC system shows a crankcase heater not heating error, it means the heater band wrapped around your compressor base has failed and is no longer providing the necessary warmth to keep refrigerant oil fluid during off cycles. This open circuit in the heater requires replacement of the entire heater band to prevent compressor damage and ensure reliable system startup.

How to Fix Error Code Crankcase heater not heating

  1. Turn off power and locate the compressor

    Always disconnect power before working on HVAC equipment to prevent electrical shock or injury.
  2. Test the crankcase heater with a multimeter

    Ensure the unit has been off for at least 30 minutes to allow components to cool before testing.
  3. Remove the old heater band

  4. Install the new crankcase heater band

    Do not overtighten the heater band as this can damage the compressor or the heater element.
  5. Connect electrical wiring

    Double-check wire connections against the unit's wiring diagram to prevent damage to the control board.
  6. Test the new heater installation

    The heater surface will become hot during operation - avoid direct contact after energizing.
  7. Reassemble and verify operation

When to Call a Professional

Contact an HVAC technician if you're uncomfortable working with electrical components, if the compressor shows signs of damage, if refrigerant lines need to be disconnected for access, or if the error persists after heater replacement as this may indicate control board or wiring harness problems.

Frequently Asked Questions

How do I know if my Goodman crankcase heater is bad?
Test the heater with a multimeter - a good heater should show 15-50 ohms resistance. An open circuit (infinite resistance) or very high resistance indicates a failed heater that needs replacement.
Can I run my Goodman HVAC without a working crankcase heater?
While the system may run temporarily, operating without a functioning crankcase heater can cause refrigerant to migrate into the compressor oil during off cycles, leading to poor lubrication and potential compressor failure.
Why does my Goodman crankcase heater keep burning out?
Repeated heater failures often indicate electrical issues like voltage spikes, incorrect voltage supply, or problems with the control board that regulates heater operation. Have an HVAC technician check the electrical system.
How much does it cost to replace a Goodman crankcase heater?
Crankcase heater bands typically cost $25-75 for the part. Professional installation ranges from $150-300 depending on accessibility and local labor rates.
Should the crankcase heater run all the time on my Goodman unit?
Most crankcase heaters are designed to run continuously when the compressor is off to maintain proper oil temperature. Some newer systems may cycle the heater based on outdoor temperature or system demand.
