Igniter Circuit Fault
No LED / Dark Board
Amana furnace is completely dead; no LED lights, no blower or inducer operation.
No Power to Furnace
Steady ON
Status LED on Amana furnace control board is solid ON with no flashing pattern, but furnace does not operate correctly.
Normal Operation Indication / No Call for Heat
Symptom
Furnace blower runs continuously, even when there is no call for heat or cool.
Blower Stuck in Manual/Continuous Mode
Symptom
Furnace cycles on and off rapidly (every 30–90 seconds) without reaching temperature.
Thermostat or Flame Sensing Short Cycle
Symptom
Furnace does not start when thermostat calls for heat, but LED shows normal and 24V is present.
Failed Control Board Output
Symptom
Furnace emits a burning dust smell at the beginning of the heating season.
Dust Burn-Off
Symptom
Furnace frequently trips the household circuit breaker.
Electrical Overload or Short Circuit
Symptom
Furnace ignites and runs, but blower starts very late, causing very hot air and frequent limit trips.
Improper Blower On/Off Timing
Symptom
Furnace inducer motor runs but burners do not ignite; no error code displayed.
No Ignition / Gas Flow Failure
Symptom
Furnace is very noisy in the flue/vent area, with roaring or whooshing sounds.
Vent Airflow or Combustion Noise
Symptom
Furnace makes loud booming or delayed ignition noise when burners light.
Delayed Ignition
Symptom
Furnace occasionally emits a brief puff of smoke or odor from registers at startup.
Minor Combustion Byproduct / Dust in Ducts
Symptom
Furnace operates but carbon monoxide detector in the home alarms.
Combustion / Venting Safety Hazard
Symptom
Furnace produces a high-pitched whine or squeal during operation.
Blower or Inducer Bearing Wear
Symptom
Furnace produces a strong metallic or electrical burning smell.
Overheating Electrical Component
Symptom
Furnace rattles or vibrates loudly when running.
Mechanical Vibration / Loose Components
Symptom
Furnace runs but airflow from registers is weak.
Restricted Airflow
Symptom
Furnace runs but delivers insufficient heat; home never reaches set temperature.
Underfiring / Low Heat Output
Symptom
Furnace runs but thermostat temperature overshoots setpoint by several degrees.
Overheating / Thermostat Calibration Issue
Symptom
Furnace short cycles: starts, runs for a few minutes, then shuts off and restarts frequently.
Short Cycling Due to Overheating or Control Issues
Symptom
Furnace starts but shuts down within a few seconds; blower may or may not start.
Flame Establishment Failure
Symptom
Water leaking around the base of a high-efficiency Amana furnace.
Condensate Leak
