Possible Causes

Miswired W1/W2 terminals, Open safety circuit on Amana furnace (limit, rollout), Failed gas valve or heat strip relay, Thermostat configured for wrong heat source

How to Fix / Troubleshooting

Safety first: Turn off power and gas (if applicable) before opening furnace panels. Gas and high-voltage components should be handled by professionals.

  • Step 1 – Verify thermostat configuration: Confirm the thermostat is set for the correct type of heating (gas/oil vs. electric vs. heat pump) in the installer menu.
  • Step 2 – Check W wiring: Ensure W1 (and W2 if used) are correctly wired at both thermostat and Amana control board.
  • Step 3 – Observe furnace status lights: Many Amana furnaces flash diagnostic codes. Note the pattern and refer to the furnace manual.
  • Step 4 – Do not bypass safety switches: If a limit or rollout switch is open, it indicates an unsafe condition. Do not jumper these; call a professional.

When to call a professional: Any issue involving gas valves, heat strips, or safety switches should be handled by an HVAC technician.
