What ERR04
actually means.
ERR04 on the oven display of a Hestan KRD dual-fuel model is one of the codes Hestan calls a non-critical electronic malfunction. One feature may stop working, but the oven itself can still be used.

What to do when ERR04 shows on the ovenKind 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.
Each step comes from Hestan's own guidance for ERR04 on its ovens. Follow it to the end: the last card says whether this is a visit.
Switch the circuit breaker for the appliance off, then back on, as Hestan suggests.
If ERR04 is gone, carry on cooking; note that it appeared.
If ERR04 stays, use the oven without the missing feature and book a visit soon.
What not to do
ERR04 is not in the critical group. Any code Hestan does not list with ERR04, ERR05, ERR08 and ERR20 counts as critical, and then the oven should not be used.
