Amana EEd is the auxiliary limit in the blower compartment. The furnace does not operate. The chart says to check filters and ductwork, blower speed or a failed blower motor, and the wiring. The filter is the homeowner step, with power off. EE3 is the primary limit, also with a filter step, and on EE3 the circulator is described as running continuously. EEd is the blower-compartment switch.

Likely causes

  • Blocked filters or ductwork
  • Circulator blower speed or a failed blower motor
  • Loose wiring in the auxiliary limit circuit

Safe checks for EEd

  1. With power off, check the filter and replace it if it is blocked. Open registers that are shut
  2. Techniciancheck circulator blower speed and performance, and the auxiliary limit wiring
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 if EEd returns after the filter and registers are clear. This is the blower-compartment auxiliary limit, not the primary limit code EE3.
