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.
