Answer Hello Paul. Test the thermostat with a multi-meter and see if it is bad and needs to be replaced. If it is good, replace the board. We will need your model number to help you more with this. Please call 1-877-477-7278 or post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx Read More...
