Mars for Model Number RF378LXPQ1 I'm at the end of my rope. I've got an oven that does not heat to 350 during the normal pre-heat time (6 minutes). There are no error codes. I've attempted to replace the oven sensor and this control board with no change. I've changed both broil and bake elements (old sensor and control board)...no change. Is there anything else a DIYer can do to fix this? I've seen checking the voltage at the elements to see if they're at 220-240VAC, but am drawing a blank as to what to check across (ground to one side of element terminal?) Let's just assume facts not in evidence and say it's not at 240VAC as it should be, is that some sort of relay or fuse that can be replaced? Please help. Thanks.
Answer Hello Mars. You will test from one side of the element to the other side of the element. Do not test to ground. You should have 240 volts. If not, you will need to test from the control and see where you are loosing the voltage at. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
