Good Morning/Afternoon Gurus.

We have a Kenmore Convection Oven Model #790.42003603.

Top oven on Bake selection keeps consistently beeping when heating up/ going to selected temperature.

I can hear relay clicking like it is trying on and off heating element.

As soon it is reaching desired temperature it stops.

As soon as temperature is going down, it starts consistently beeping again in a sequence of short beep (temperature selection), long beep (desired temperature reached) and supporting by relay clicking sound with each beep (short and long). No Error Codes displaying.

 

For me, looks like relay responsible for turning on/of bake heating element in top oven is failing on the board.

 

However, this dude has 5 boards:

316460300 - excluding, as it looks like it is a use interface board (Control Panel Diagram)

316435701 - excluding, as it looks like it is a power board (Control Panel Diagram)

316460201 - (Control Panel Diagram)

316443910 - (Upper Oven Diagram)

316460901 - (Upper Oven Diagram)

 

 Any suggestions which board is causing this behavior? I am leaning toward main board  316460901, but need your highly experienced opinion.

 

Thank you!!!

I don't know the answer right now... will have to think about it ..

but, it may be a bad Oven Sensor

Could try swapping the upper and lower Oven Sensors

i have not seen that happen with a failed sensor. Sounds like the board's brain is scrambled. Bro Reg's suggestion is a good one to eliminate sensor as the culprit .
Appliantology is, however appliances are not, an exact science for I know there are a few refrigerators that actually hate me.

The simplest explanation is most likely the correct and least expensive one, unless it's your compressor or motherboard" Occam as an appliantologist

"When you have eliminated all the impossible, whatever remains, however implausible, must be the logic truth; unless it's your compressor or motherboard." Mr. Spock as an appliantologist

I think Reg might be right.  There was a service bulletin on the 30' Frigidaire freestanding ranges addressing a beeping sound from the control section with no fault codes displayed.  The culprit was the mini oven sensor being open or shorted, as well as an over temp issue.  I'll keep checking.

Thank you all for a great suggestions.

We are checking if the issue is resolved.

This is what we did:

1. replaced relay board - initial beeping eliminated during pre-heat. As soon as it pre-heated and temp going down, long - short beeps are continues.

2. exchanged heat sensors between lower and top. (did not installed new) - issue is completely resolved. Both units are working normally without beeping. (mystery) However, when running both ovens and turning them completely off, got "Err" displayed. No number, just "Err". It happened only 1 time and we cannot re-produce it again. Will be checking with a customer after a while.
