Wolfbabe for Model Number RB525S1WH HOTPOINT OVEN HEATING UP ON IT'S OWN Our Hotpoint oven is about 25 years old and this is the first problem we've really had with it (that either means it's well made or I don't cook a whole lot...maybe both) The bottom heating element burned out with lots of sparks and noise about a week ago. We turned the oven off right away but the element continued to glow red then white so we turned it off at the breaker. The element has now been replaced with a new one but as soon as the breaker was turned back on the element began to heat up (the oven temperature knob was still in the off position). I turned the temp knob on and set it to 350 degrees. The oven continued to heat up and when it passed 250 (I have one of those thermostats that hangs inside the oven) I turned the knob down to 225 to see if it would click off and it did (good sign). I turned the temp dial to off and the oven turned off (oven light went off and it stopped heating up). We thought everything was ok until several hours later I heard the oven click like it does when it gets to the right temperature. The oven was off and had been for several hours. When I opened the door it was warm and the hanging thermostat read 150. We tried turning it on and off again but it did not click off this time. Also, my husband was able to turn the dial past Broil where it normally stops. We turned the breaker off again to make sure it stayed off. Does it sound like we need to replace the oven thermostat? I found part #WB21X5287 but I want to make sure that's the problem since it's expensive. How can we check? Would replacing this also fix the dial's ability to turn past the Broil setting or is that another issue? Thanks in advance for your help!
Answer Wolfbabe, you may want to check to ensure that the thermostat is not sending 120VAC to the element when it is in the off position. If it is, then you definitely have a bad thermostat [WB21X5287]. Another thing that can cause the unit to heat up when in the off position is if the element is grounded out. You can test to see if the element is grounded by disconnection the power and testing for continuity. If the element tests for continuity from the element to the oven frame, then you have a grounded wire. Read More... Answered by AppliancePartsPros.com | Monday, March 4, 2019
