Safe first steps, before the call. Nothing here needs a tool.
If you smell gas: don’t touch any switch or plug, leave, then call the gas company or 911 from outside.
No gas smell? Note what the noise sounds like and when it happens, then turn the oven off and switch off its breaker.

Everything else about this problem
Is it an emergency?
Is a loud noise from a Kenmore oven an emergency?
Usually not an emergency. A grinding, rattling or humming that has just started most often comes from a fan, motor, belt or loose panel. Stop using it and cut the power if the noise comes with a burning smell, smoke or sparks; if it runs on gas and you smell gas, leave and call the gas company or 911 from outside.
Symptoms & causes
Loud noises from a Kenmore oven often manifest as buzzing, humming, rattling, or grinding sounds, typically originating from the rear or top of the appliance. These noises are frequently caused by a failing convection fan motor, a worn-out cooling fan, or a loose fan blade hitting its housing. Over time, the bearings in these motors can degrade, leading to increased friction and the characteristic loud operational sounds.
Tools & parts
For testing and repair, you will need a basic screwdriver set, a nut driver set, and a multimeter to test electrical components. Common replacement parts include a Kenmore convection fan motor or a cooling fan motor. An oven igniter may need replacing if it clicks loudly; always use brand-specific Kenmore parts for compatibility.
Safety first
Before attempting any inspection or repair on your Kenmore oven, always disconnect the electrical power at the circuit breaker and shut off the gas supply valve if it's a gas model. Failure to do so poses severe risks of electrical shock or a gas leak, which can lead to fire or explosion. Even after power is off, oven components can remain hot, so wear protective gloves and allow ample cooling time to prevent burns.
When to call a pro
If your Kenmore oven's main control board is suspected to be faulty, or if there are issues with the gas valve, professional assistance is absolutely required. Complex electrical tests beyond basic continuity checks, or any suspected gas leak, warrant immediate attention from a certified technician. Should the noise persist after basic component checks and replacements, or if specialized tools are required for deeper access, it's time to call a Kenmore service expert.
Questions people ask
Why does my Kenmore oven make a loud humming noise?
A loud humming noise from your Kenmore oven is most often indicative of a failing convection or cooling fan motor. The bearings within these motors wear out over time, causing increased vibration and a distinct humming sound during operation.
Can a loose fan cause loud noises in my oven?
Yes, a loose fan blade, particularly the convection fan, can cause significant noise by hitting its housing or other internal components. This often results in a rattling, thumping, or scraping sound as the fan spins.
Is it safe to use my Kenmore oven if it's making loud noises?
It depends on the noise; a minor rattle might be harmless, but grinding, buzzing, or electrical clicking could indicate a serious issue that poses a safety risk. It's always best to track down and fix the problem promptly to prevent further damage or potential hazards like electrical shorts or overheating.
