Goodman Furnace Code EAL
Safety fault
On an R-32 refrigerant system, the leak sensor detected refrigerant and put the furnace into mitigation mode - the blower runs to disperse it and normal heating is suspended.
Manual wording: “R-32 sensor has detected a refrigerant leak and furnace is in mitigation mode.”
Documented for: Goodman GMVC96, GCVC96, GMVM97, GCVM97, GM9S80, GC9S80, GR9S80, GD9S80, GR9T96, GD9T96 (seven-segment display controls)
Likely causes, most common first
- Refrigerant leak at the indoor coil
What you can safely check yourself
- Leave the furnace powered so the blower can keep running in mitigation mode
- Call for service - do not disable the sensor or the mitigation blower
When to call a technician
A refrigerant leak at the indoor coil is a technician repair. The furnace clears the code on its own once no leak is detected and the 5-minute delay ends.
A Goodman furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
