My dryer was running today perfectly fine and it randomly stopped running while the timer was still in the middle of a cycle. Could not ever get the dryer to turn back on.

I think I’ve narrowed it down to two possible issues.

So far I’ve checked:
Power from wall
Door switch(didn’t work for 2 years just stayed permanent closed until a month ago I finally had to replace)
Heater fuse
Start switch
Belt

1st of my two possible problem parts is the Dryer timer switch. I watched https://m.youtube.com/watch?v=wC3ZKbhhAZA which claims W-T should be switched and read close to zero, I’ve tried spinning the dial, Mine is open no matter what on that side.
However, I tried jumping these two wires and that did nothing, not sure if it would be that simple, but I’m going with no.

2nd is the dryer motor, schematics shows it should have 2.3-3.8 Ohms resistance but I’m reading 1.5 Ohms - assuming I’m reading from the correct terminals which I believe strongly I am.

Where do I go from here? I’m close to just getting a new dryer but figure I would try to save this old Roper for a little longer.

Do you hear the motor trying to do anything? IME when electric motors die, you can often hear them trying to start. I would assume you could get the meter down at the contacts and see if the motor gets power as somebody else presses the “start” button. If it’s a straight 120VAC motor, maybe you could jump power straight to the motor as well, but I’m not 100% on that, it’s the type of shit I would do on a 12V automotive circuit all day.

You should be able to get continuity at certain contacts at the timer switch, that sounds like it could be the issue.

Although if you’re jumping wires at the timer and still get nothing, it’s very possible you’re missing a fuse or the power in is bad. I had a faulty circuit breaker that was ok sometimes and then 10V-40V on one of the legs at another time and I wasted a bunch of time checking everything inside the dryer before opening the breaker panel and seeing an arc across the breaker as somebody started the dryer.

No I don’t hear the motor doing anything at all, didn’t sound weak or act funny before all this occurred. I need to try spinning the drum while I press start. It is possible to jump power directly to motor but I don’t have my huge selection of cut cords/test material/tools etc at my house - still at my parents. That’s probably a safe way to determine if it’s good or not but I’m ready to do all that.

Yea the timer confuses me, the continuity appears to be an issue but not being able to jump is weird.

I’ve checked both sides of the wall outlet and both have 120 and the combined is 240. Haven’t tried opening breaker panel yet. That’s probably my next test

Already replaced a month ago, I’ve rechecked it 3 times since this happened yesterday and it works perfect.

I'm going to guess that the metal contacts inside the timer are fucked. Maybe you could open it up and inspect it visually and see if some contact cleaner in there might help.

brand model and year?
80% of the time with a dryer it's a fuse or a loose/melted contact
they always clog up with lint and overheat
ALWAYS
15% of the time the belt breaks or slips from being worn

Bad thermal fuse I bet. Try removing the fuse and inserting a piece of wire to test.

>No I don’t hear the motor doing anything at all,
There's a tensioner on the belt that if the belt breaks it will extend to an overload state that will cut power to the motor.
You need to tip the dryer over onto its front and see if the belt is still intact around the drum. Mine recently snapped and without the belt in place nothing inside the dryer will turn on.
They're very cheap to buy and replacing it generally just involves taking off the front face of the dryer so you can wrap the new belt over the drum and thread it onto the tensioner and drive pulley on the motor.
