Greg for Model Number LSB5611SS _Oven set for 350 deg. _Oven overheats to nearly 500 deg and keeps climbing, indicated by portable temp gauge in oven, burns up whatever is in the oven. _Does not regulate temp. _Shutoff oven from front panel. It is really really hot over the 350 deg. as shown on the display. (1) Changed the expensive processor Bd. - Same overheat problem. (2) Checked the Thermistor at room temp. - is 1090 ohm (within range). The only thing left is the relay board (quite expensive). Do you recommend replacing the relay bd. ?, or is there some other component thats affecting the oven overheat problem ?. Heard that the broiler plays a part in pre-heating the oven ?. Do you believe that it is the relay bd is the problem Thanks for your help.
Answer Greg, Based on what you have told us, the control board with the bake and broil relays would need to be replaced.6871W1N012B Read More... Answered by AppliancePartsPros.com | Monday, June 29, 2020
