What F20
actually means.

F20 appears on the oven touchscreen of a BlueStar dual-fuel model as Control Error F20. BlueStar ties it to the control board or its wiring, the electronics that run the oven's modes and heat.

What to do when F20 shows on the oven

Kind of codeCommunication

The display and the main control board stopped hearing each other, or the board failed its own check. A power dip, a loose ribbon cable or moisture behind the panel is ruled out before either board is replaced, and an oven that stays on through this code is switched off at the breaker.

Usually leads toControls and sensors

Dead keys, a blank or garbled display, an oven that will not switch off or will not respond, traced to the board, the touch panel or their wiring.

Shows up asOven Control Panel Not Responding

The touch controls or buttons do nothing, the display is blank, or some keys work and others do not.

Before you book,
in this order.

01

Note F20 and what mode the oven was in.

02

If F20 comes back, book a visit.

Still there?

It usually turns into controls and sensors. Book with the code and the model number.

What not to do

F20 is not a sensor or probe code; BlueStar gives those their own numbers. It points at the electronics themselves.

Questions
about F20.

Can I clear F20 myself?
Note F20 and what mode the oven was in. If it comes back, it needs a visit.
Does F20 on a BlueStar oven mean the board has to be replaced?
Not necessarily. BlueStar names the board or its wiring, and a loose or damaged connection is checked before the board is condemned.
Can I keep cooking in a BlueStar oven while F20 is on the screen?
The code means the controls themselves are in question, so settings may not be carried out. Wait for a technician before relying on the oven.

Back to your everyday

Still showing F20?

Book with the code exactly as shown, the full model number, and whether you can smell gas or burning — with a code, that is where the diagnosis starts.
