Nick for Model Number JVM1790SK01 The knob turns and works sometimes to set the minutes but we have to wiggle it a bit. To start to oven you have to press this knob in; this again has been a problem, we have to press very hard to get it to start. It looks like for what should be just a small switch you have to replace the whole controller board. Is that correct? Thank you!!
Answer Hello Nick! Yes, you will need to order the board assembly WB27X10866. Make sure that the knob is not warping. Thanks! Read More... Answered by AppliancePartsPros.com | Monday, July 30, 2012
