I am trying to find out if I can test the timer to my Whirlpool dryer (model LER7646JQ0) to find out if it failed or not. I have already replaced the thermostat and was about to replace the heating element and found out by testing it with an ohm meter that it did not need replacement. Is there someway I can test the timer to see if it's bad? The reason I think the timer is bad because I tested the heating element while the dryer was running and was only getting 110 from the two legs and not 220. So I removed the two wires from the heat element turned on the dryer and checked each wire. One wire read 110 that looks like it goes to the moter. The other wire wich is a jumper from the thermal cutoff got no reading. Followed that wire, (orange in color), to the timer on the front panel of the dryer. Hope this makes sense. Any help would be appreciated.
Check if you have 220 at the terminal block. The power is 220 hot to hot and 110 for each leg to ground. Generaly the has two speeds (220 regular and 110 for gentle). There are two heating elements that are ciontrolled the same way. The gentle cycle uses one leg and the heat ing elements use the other. The answer is how the dryer is set. Knowing that and using elmination you will find the problem in the controlls because the heating elements work or thew are open. The motor has two windings or it works or it works or has an open. I could not find a schematic but you may see it on the back oe a piece of paper in the controlls. I have faith in you finding the problem very quickly from what you said and what I told you. Good luck. Don't forget to cycle (turn them off and on) your breakers to make sure one is not intermittent.
I do not think a "NO HEAT" problem can be caused by the timer.
Sounds like another electrical problem:
Have you check the house breaker or wall receptacle to see if you are feeding 220V to your dryer?
Have you check your hi-limit thermostat to see if it has continuity?
Those are the most common causes of "NO HEAT"
