Symptoms
- Racks feel gritty or catch when sliding in or out
- Visible grease or residue buildup on the rack rails
- One rack position is worse than others
- Racks squeak loudly when moved
Likely causes
- CommonBaked-on grease and food residue on the rack railsGrease buildup on the metal rails creates friction and grit that makes racks harder to slide.
- PossibleWarped rack from heat exposure over timeA rack that's slightly bent no longer sits evenly on the rails, causing catching.
- PossibleBent or damaged rail/guide inside the oven cavityA guide rail knocked out of shape can cause consistent sticking at that position.
- Less commonRust developing on rails or racks in a humid environmentRust can create rough texture that catches as racks slide.
What to do
- Remove all racks and set them aside for cleaning.
- Wipe down the interior rail guides with a damp cloth and a degreasing cleaner to remove buildup.
- Clean the racks themselves with warm soapy water and a scrub brush, or run them through self-clean if manufacturer-approved for your rack type.
- Dry the rails and racks fully before reinserting.
- Slide each rack in and out a few times to test smoothness after cleaning.
- Inspect for any visible warping in the racks or bending in the rail guides if cleaning doesn't fully resolve sticking.
- Replace a warped rack or a bent guide rail if that's identified as the specific cause.
