Goodman GMVC960803BN Error Code EE7: Igniter Fault or Improper Grounding
What Does Code EE7 Mean?
Error code EE7 on the Goodman GMVC960803BN indicates that the integrated control module has detected a fault in the igniter circuit. The furnace cannot proceed with an ignition sequence and will not operate until the condition is resolved.
The igniter circuit fault can have several origins. A shorted hot surface igniter — one whose resistance has dropped abnormally or whose element has cracked and is contacting a grounded surface — will cause the control to report EE7. An improperly connected igniter harness, such as reversed polarity or a plug that is not fully seated, can produce the same result. A poor or missing unit ground is another cause: without a proper ground, the control module cannot accurately sense the igniter circuit conditions and may report a fault. Finally, the igniter relay on the control board itself may have failed.
A technician will measure the igniter's resistance with a multimeter, inspect the wiring harness for damage or misconnections, verify the unit is properly grounded, and test the igniter relay on the control board to isolate the fault.

When to Call a Professional
Contact a licensed HVAC technician if:
- EE7 is present — the igniter circuit must be tested with a multimeter and the wiring inspected before the furnace can be safely operated
- The hot surface igniter tests shorted or with abnormal resistance — it must be replaced by a technician
- The unit ground connection is missing or corroded — proper grounding must be verified and restored
