UNPLUG/SECURE BREAKER FIRST!!! Removed all screws on the back, disconnected the three wires (two red, one white) from the element assembly, removed the two screws holding the asmy in. Had to remove the thermostat and swap it over to the new. Installed new asmy and reconnected the two red and one white; no problems encountered. Replaced the timer asmy about 2 months ago and then the heater core goes. Indicator when the timer goes: it buzzes. The main contact (BK/BU) did not open fully (burnt), the timer motor had 1/2 voltage (100 or so volts), which allowed it to buzz. Initially burnished (sanded) the contacts but the problem came back. Saw it as fire hazard, since it didn't secure the power to the whole system; so it was replaced. They've been the only two parts to go, the rest of the dryer is still holding strong. If your dryer is over 5yrs, recommend you vacuum it out the inside of the cabinet and inside the exhaust/fan chamber. It takes a little work to get the chamber open (double sided sealing tape) around the exhaust port for the drum, but worth it in the long run (reduces the chance of a lint fire in the exhaust chamber).
