Amana Furnace Code E10
Soft lockout
Grounding fault. The control does not see a good neutral or ground connection to the furnace and will not operate.
Manual wording: “Grounding fault. Poor neutral connection.”
Documented for: Amana AMVC96, ACVC96, AMVM97, ACVM97, AM9S80, AC9S80, AR9S80, AD9S80, AR9T96, AD9T96 (seven-segment display controls)
Likely causes, most common first
- Poor neutral connection
- Loss of continuity to the ground source
When to call a technician
Neutral and ground continuity is electrical work at the furnace and the panel. Call the installer or an electrician.
A Amana furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
