Symptoms
- No noticeable difference in cook time between convection and regular bake
- No fan sound heard during a convection-selected cycle
- Food browns the same regardless of mode selected
- Convection indicator light shows on but no apparent fan operation
Likely causes
- CommonConvection mode not actually selected due to a menu navigation mistakeSome ovens require pressing a specific 'convection' or 'true convection' option separately from just setting a temperature.
- CommonConvection fan motor failureA dead or disconnected fan motor means no air circulation even if convection mode is selected.
- PossibleNot adjusting temperature or time for convection as intendedConvection often cooks faster at the same temperature, so results may seem 'off' rather than 'no different' if not accounted for.
- PossibleObstruction blocking the fan from spinningA dish or foil placed too close to the back vent can physically block the fan.
What to do
- Double check your oven's manual for the exact steps to select convection or true convection mode, since it's often a separate button press from setting temperature.
- Listen closely for a fan sound after starting a convection cycle by placing your ear near the door (careful of heat).
- Remove any dishes or bakeware placed directly against the back wall vent, which can block the fan.
- Try convection with a small test item like cookies on two racks to see if you notice faster or more even browning compared to a past regular bake.
- If you can't hear or feel any air movement with the door slightly cracked before it heats up, the fan itself may not be running.
- Unplug and visually check accessible fan blade (once cool) for obvious damage or looseness if you're comfortable doing so.
- Have a technician test and replace the convection fan motor if you confirm it isn't running during a convection cycle.

When to call a pro
If you confirm the convection fan isn't running during a selected convection cycle, have a technician replace the fan motor.
