When it gets to temp it trips the breaker,how do I know what part to replace?
Answer Hello Missy,
You will first want to check to see if the heater is touching ground. Also check for other wires for broken or damaged wires. If the heater is being grounded replace the heater.
My dryer doesnt heat up at all. Should I replace the heater assembly or start with something else?
Answer Hello Jason. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater Y303778 and thermal fuse 303396 and see if they are good. You can test these with a multi-meter TJMA-DM1. They should read closed for continuity. 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
