What COOL FAN Means
This code means the oven's control board isn't getting a valid speed signal from the cooling fan — the fan responsible for keeping the control electronics from overheating during a bake or self-clean cycle.
Common Causes of COOL FAN
- A failed cooling fan motor
- A failed speed sensor on an otherwise working fan
- A wiring problem between the fan and the control board
🔧 One Safe Check You Can Try
Listen for the cooling fan during operation — it usually runs during and for a while after a bake or self-clean cycle. If you can't hear it running at all, that supports a fan problem; if it sounds like it's running, the issue may be the speed sensor rather than the fan itself.
⚠ Why You Shouldn't Go Further Than That
- The cooling fan protects the control electronics from heat damage — continuing to run bake or self-clean cycles with a confirmed fan problem risks a much larger electronics failure.
- The fan and its wiring are positioned near line-voltage connections, so testing them without isolating power first is a shock risk.
- Installing a replacement fan with the wrong specification can leave the electronics under-cooled even though the error code clears.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
