Brian for Model Number LER6620PQ0 My original timer would advance but the dryer wouldn't shut off. Even if I manually turned the timer to the off position. I installed a new timer. The new timer won't advance so installed a new thermal cutoff kit. The timer still won't advance. On any setting. Vent is clear and the dryer will shut off now if I manually turn it to the off position. It just doesn't advance. I'm not sure if I have a bad timer or what is going on. Any help would be appreciated. Thanks again for your help.
Answer Brian, if the dryer is heating properly, the timer would need to be inspected to ensure the wires are set at the necessary terminals as the timer motor uses 240VAC to advance in an electrical dryer. If the wires check to be properly set and the timer shows 240VAC from terminal BK to terminal WB during a timed dry cycle, the timer WP8299778 has an internal failure. Read More...
