Amana Furnace Code EED
Warning
Auxiliary limit switch in the blower compartment is open. Like the main limit, this is an overheat trip caused by poor airflow.
Manual wording: “Aux limit switch open (blower compartment)”
Documented for: Amana AMVC96, ACVC96, AMVM97, ACVM97, AM9S80, AC9S80, AR9S80, AD9S80, AR9T96, AD9T96 (seven-segment display controls)
Likely causes, most common first
- Blocked filters
- Blocked or restrictive ductwork
- Improper circulator blower speed
- Failed circulator blower motor
- Loose or improperly connected wiring
What you can safely check yourself
- Check the air filter and replace it if dirty
- Open all supply registers and clear anything blocking them
- Make sure the return air grille is clear
When to call a technician
If it repeats after a clean filter, the blower or duct system needs a technician. Never jumper a limit switch.
A Amana furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
