In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
No gas smell? Switch the furnace off at the thermostat and at its breaker.
Don’t use it again until it’s checked, and keep people away from it.
Everything else about this problem
Is it an emergency?
Is a Maytag furnace that won't start an emergency?
Usually not, but it can be. Because this can be an emergency, leave it off and get it checked; don't reset it or turn it back on. Stop and call a pro if it keeps tripping the breaker, smells like burning, or you smell gas.
Symptoms & causes
A Maytag furnace that won't start typically exhibits no heat output, a completely silent unit, or a fan that runs continuously without ignition. Common indicators include a lack of a glowing ignitor, no flame, or the thermostat displaying a 'call for heat' but no furnace response. Root causes often stem from power supply issues, a faulty thermostat, a tripped safety limit switch, or problems with the ignition system components.
Tools & parts
A multimeter is essential for testing electrical components like voltage and continuity, alongside a basic screwdriver set for accessing panels. Specific Maytag replacement parts like a hot surface ignitor, flame sensor, or a new control board might be needed for repairs. A wire brush for cleaning sensors and a flashlight for inspecting dark areas are also highly recommended.
Safety first
Always begin by shutting off all electrical power to the Maytag furnace at the main breaker panel and the furnace's dedicated service switch to prevent electrical shock. Next, locate and close the manual gas shut-off valve on the gas line leading to the furnace to prevent gas leaks. Be cautious of sharp edges inside the furnace and components that may be hot, even if the unit is off.
When to call a pro
If error codes indicate a complex control board failure or extensive wiring issues beyond simple connections, professional assistance is crucial. Any suspected gas leaks, issues with the gas valve, or problems with the combustion chamber should immediately prompt a call to a certified HVAC technician. Furthermore, if multiple components appear to be failing simultaneously or you lack the specialized tools for advanced tests, a professional can ensure safe and effective repair.
Questions people ask
Why is my Maytag furnace not getting power?
First, check the circuit breaker in your home's electrical panel to ensure it hasn't tripped; reset it if necessary. Also, verify that the furnace's dedicated power switch, usually located on or near the unit, is in the 'On' position.
What if my Maytag furnace clicks but doesn't ignite?
This often points to a faulty hot surface ignitor that isn't glowing or a dirty flame sensor that can't detect a flame. Inspect both components for visible damage or carbon buildup, which can prevent proper ignition and flame sensing.
How do I reset my Maytag furnace?
To reset your Maytag furnace, turn off the power to the unit at your home's circuit breaker for at least 30 seconds. Then, turn the breaker back on; this can clear minor error codes and allow the control board to restart its ignition sequence.
