After working fine for several years, my electric Jenn-air oven (JDS9860AAP) suddenly heats very slowly (1 hr to 350 degrees). You can hear a relay click on, then off after 5 seconds or so, then on later and off, etc. The broil element does not heat on any setting. The bottom element heats, but never red hot, and shows 20 ohms resistance. All other functions seem to work. Temperature probe measures about 1100 ohms. Control board? Relay board? How to check further? All thoughts appreciated.

Here are a few tips from the service manual

No oven operation in bake or
broil.
No voltage to control. ................................
No voltage from control .............................
Loose wire connection or broken wire.......

•

Check for 120 VAC at control. If no
voltage check power source.

•

Check 120 VAC to ignitor, if no
voltage, replace control.

•

Verify all connections are clean and
tight, replace broken wire.

No bake element operation Open bake element...................................
Loose wire connection or broken wire.......
Open bake relay........................................

•

Check element for continuity,
replace if failed.

•

Verify all connections are clean and
tight, replace broken wire.

• Verify 240 VAC at bake element.

No broil element operation Open broil element ..................................
Loose wire connection or broken wire.....
Open broil relay .......................................

•

Check element for continuity, replace
if failed.

•

Verify all connections are clean and
tight, replace broken wire.

• Verify 240 VAC at broil element.

See if this helps any.

Thanks for posting the service manual steps. These will give me a logical series of tests to conduct. Much appreciated.

Thanks again for posting the service notes. Followed them and the one that helped most was checking the elements for 240 volts. Turned out there was only 120 volts present, then traced that issue to a faulty relay on one side of the high voltage supply. $8 part and we are back in business!

Glad it helped you.
