Heat circuit runs through thermostats and fuses (most dryers have 4), timer, heating element, and motor. Could be any one of those. Also insure you have 240 volts going to dryer.
that could be a few different things ,broken belt,there's a switch on the belt pulley that stops the dryer from starting as a safety if the belt breaks,you didn't send the model number next time send it,open the door,look around the opening where you put the clothes in and you'll see a tag with the model number on it,could be a bad thermal fuse,high limit thermostat,the only way to tell is by getting in there with a meter and check it,the easiest thing to do is take the lid off and grab the belt and pull on it to see if it broke,check the door switch,push it in and out and make sure it's working,also on the back where the cord connects make sure you have 240 volts there if it's electric,if it's gas then you know you already have power because the light is on.if you need more help send model number and do a few checks and i can help you out.also have you seen any error codes come up,if so send them.
My GUESS is the machine was either operated without the lint screen and an item made its way near the exhaust fan or piece of the lint screen itself has broken loose and made its way near the fan. The sand noise would likely be debris being swept up by what ever got into the fan duct, then through the fan leaving the item stuck near the fan. I suppose it would be possible for lint to build up in the internal duct and it dislodged... but not likely unless poor exhaust or extreme exhaust vent length. But I would expect other complaints if that were the case.
Yes you want to see if the heating element is turning on and off but no flame is being lit. You might have to take the casing off to see it. There are two coils that open the gas valves one with 2 wires and one with three wires I believe. One of the coils is most likely the problem. Use a digital multimeter, it's your friend.
Retest the breaker. One side can trip without moving the handle. This will stop 240 to the element but still operate everything that operates at 120 volts.
Likely a failed control board or supply to control board. It could be loose cable. The control board is just underneath top cover of unit. Unplug unit and remove screws on backside. Disconnect/reconnect cables and see if it works.
There may be another metal cover over the control board... it's been awhile since I last worked on mine to replace heat element relay.
I found the service manual free online. Comment here for further assistance.
I could not make sense out of your model number ... however .... generally there is NOT an easy accessible "reset" button on dryers. Sometimes, with newer models there is a sequence you can through with the control panel like the first video. Or just unplugging it ... waiting 10 minutes ... then replugging it back in.
But if you have over heated the dryer (too much lint build up as an example) there is an internal high temperature limit fuse that blows to prevent the dryer from overheating.
See second video as an example of that.
Good luck with your troubleshooting!
When was the last time you checked the dryer vent and tube leading out of the home? Move the dryer away from the wall. With the dryer unplugged remove the duct from the wall attachment. Use a vacume hose to reach as far into the wall vent as possible sucking out any debris. Do the same with the hose on the back of the dryer. If there's alot or it's been a very long time since it's been done, I'd suggest consulting a professional. Mine was so bad when I moved into my place, birds had nested in there. Ew
