I just replaced a bad heating element in my Admiral dryer due to no heat at all. I also replaced all the fuse and thermostats. I also tested voltage while plugged into power and continuity on fuse and thermostats while unplugged, which all checks out. After replacing the parts, when I plugged the dryer back in and started a new cycle the heating element came on but shut off after 1 to 2 minutes and did not come back on. I opened the dryer door to turn off the drum and closed the door reset the cycle and the heating element did not come back on at all. I have also removed all of the lint from the screen all the way out. I also disconnected the exhaust duct that goes to the wall and let the dryer vent into the laundry room to verify air flow. What else could I be missing?
You may have a problem with the timer. Not likely worth the price of a new timer as compared tp a cheap new dryer.
