An Amana furnace may use a reset button as a safety feature to restart a system after a lockout or fault. The reset button is typically part of the furnace’s safety circuit, and pressing it can help the unit begin a fresh ignition sequence once the underlying issue has been addressed. This guide explains what the reset button does, where to find it on common Amana gas and electric models, and how to reset the furnace safely. It also covers common causes for a reset, steps to follow, and indications that a professional should be consulted.
What Is The Amana Furnace Reset Button
The reset button is a safety device that triggers a restart after a fault such as a flame sensor fault, overheating, or venting issue. Pressing the button resets the control board after the underlying problem is addressed. Not all Amana units have a visible reset button; some models use a pressure switch reset or a built-in safety switch that requires a manual reset. Understanding when to use this reset can prevent unnecessary service calls and help verify that basic issues are resolved.
In general, a reset is a diagnostic restart rather than a repair. If the furnace repeatedly requires resets, the root cause—such as a dirty flame sensor, restricted venting, or a failing limit switch—needs proper attention by a qualified technician.
Where To Find The Reset Button On An Amana Furnace
In gas models, the reset button is often located on or near the pressure switch or inside the burner compartment. It may appear as a small protruding button or a recessed push button within the switch housing. Electric models may not use a manual reset button; instead they rely on a reset function on the control board accessible from the blower compartment or front panel. If a model shows a red, yellow, or orange button, this is typically the reset control. Always consult the specific model’s owner’s manual for the exact location and procedure.
For safety, ensure the furnace is powered off before inspecting the area around the pressure switch or control board. If there is any uncertainty about model-specific location, contact Amana support or reference the official manual for your furnace series.
Reasons You Might Need To Use The Reset Button
- Flame Rollout Or Sensor Error: A flame sensor or ignition fault can trigger a safety lockout that requires a reset after addressing the ignition issue.
- Overheating: Excess heat can cause a limit switch to trip, preventing further operation until it cools and is reset.
- Vent Blockage Or Restricted Airflow: Blocked or restricted venting can cause diagnostic faults and require a reset after clearing the obstruction.
- Dirty Air Filter Or Blocked Airflow: Poor airflow can lead to overheating and shutoffs.
- Gas Supply Or Pressure Issues: Irregular gas pressure or valve issues can trigger safety shutdowns.
- Electrical Or Control Board Faults: Minor electrical glitches or transient faults may respond to a reset.
Step-By-Step Reset Process
- Turn Off Power: Switch the furnace off at the thermostat and then at the main service panel to cut power to the unit. This reduces the risk of electric shock during inspection.
- Locate The Reset Button: Find the reset button on the pressure switch or control board area, as described in the model manual. Do not force components or pry panels open.
- Address The Cause: If possible, address the likely cause (clear a vent, replace a dirty filter, or ensure gas supply is steady) before resetting.
- Reset The System: Press and hold the reset button as directed by the manual, typically for 5–10 seconds, then release.
- Restore Power And Test: Turn the furnace back on at the service panel and thermostat. Listen for ignition and observe that the blower begins after a brief delay. If the furnace stays running, the reset succeeded.
- Monitor Performance: Allow the system to run for a cycle. If it shuts down again, note the error code on the control board or the furnace’s diagnostic lights for further troubleshooting or professional service.
Troubleshooting After Reset
If the furnace resets but shuts down again shortly after, perform a focused check of common fault sources. Start with air quality and ventilation: verify there is no dust or debris blocking intake or exhaust; replace or clean the air filter; ensure the condensate drain is clear (for high-efficiency models). Then inspect ignition components: the igniter, flame sensor, and related wiring for corrosion or damage. If ignition fails repeatedly, the flame sensor may require cleaning or replacement, or the gas valve timing may need adjustment. Do not ignore persistent resets, as repeated lockouts indicate an unresolved fault.
Additionally, verify control board indicators or error codes. Some Amana furnaces display fault codes that point to a specific subsystem (for example, ignition, pressure switch, or limit switch). Document any codes and consult the manual or a technician for precise interpretation. If a strong gas odor is detected at any time, evacuate and contact emergency services, as this indicates a potentially dangerous condition.
When To Call A Technician
- Repeated Lockouts: The furnace requires resets frequently and cannot complete a full cycle.
- Persistent Error Codes: Diagnostic lights or codes do not resolve after a reset and address attempts.
- Gas Odor Or Gas-Related Symptoms: Any smell of gas, hissing, or suspicion of a gas leak.
- Unusual Noises Or Smells: Screeching, banging, or burning odors that suggest mechanical wear or electrical faults.
- Electrical Or Structural Concerns: Signs of arcing, burnt wiring, or overheating components.
Maintenance Tips To Minimize Reset Issues
- Schedule Annual Servicing: A professional inspection helps identify safety device wear, clean ignition components, and verify venting integrity.
- Change Air Filters Regularly: A clean filter maintains airflow, reduces strain on the furnace, and lowers the likelihood of overheating.
- Keep Vents Clear: Ensure supply and return vents are unobstructed to maintain proper airflow throughout the home.
- Inspect Venting And Ductwork: Check for blockages, corrosion, or crushed ducts that can affect combustion and exhaust.
- Monitor Gas Supply: Ensure there are no leaks, and the gas line is properly connected and with correct pressure for the unit.
- Record And Clean Flame Sensor: A dirty flame sensor can cause frequent lockouts; inquire with a technician about safe cleaning practices.
