Amana furnace EEF: Meaning & Fix

Status codeEEFAmana

What does Amana EEF mean?

Auxiliary limit switch (condensate switch) is open. The furnace fails to operate.

How it shows: 7-segment display on a *CVC96 or *MVC96 two-stage furnace covered by IOG-2015L, including Amana AMVC96 and ACVC96: EEF

Amana EEF is the condensate auxiliary limit, the condensate switch, open. The chart's corrective action is to check the evaporator drain pan, trap, and piping. That is technician work. Do not bypass the switch. EEd is the blower-compartment auxiliary limit and has the filter step. EEF does not.

Safety firstIf you smell gas, do not touch any electrical switch or use a phone in the building; leave immediately and call your gas supplier from outside. Turn off electrical power at the furnace switch or breaker before opening any panel, and never bypass or jumper a limit, rollout or pressure switch. Gas valve, burner, venting, wiring and control-board work should be done by a licensed HVAC technician.

Capacitors can hold a charge after the power is off. Safety terms.

When to call a pro

Call a licensed HVAC technician. EEF is the condensate switch, which is a common cold-weather shutdown when the drain path is blocked or frozen.
