Thermostat is on but does not call for heating even when set above room temperature

Safety first: Turn off power to the furnace before opening panels or touching wiring.

• Step 1 – Verify mode: Ensure the thermostat is in HEAT or AUTO mode and the setpoint is above room temperature.
• Step 2 – Check schedule: Override any programmed setbacks by using a temporary hold at a higher temperature.
• Step 3 – Confirm system type: In the installer menu, verify that the thermostat is configured for the correct Amana equipment (gas furnace, electric air handler, or heat pump).
• Step 4 – Test R-W jumper (advanced): At the Amana control board, briefly jumper R to W. If the furnace starts a heat cycle, the thermostat or W1 wiring is faulty.
• Step 5 – Replace thermostat: If the furnace responds to R-W but not to thermostat calls, replace the thermostat.

When to call a professional: If the furnace does not respond to an R-W jumper, an HVAC technician should inspect the Amana ignition and safety circuits.
