Sparks coming out the back of dryer where plug is at dryer not wall

turn it off , pull the plug from the wall and call an electrician
the spark is an indication of a live wire when there should be one

May need to check ur thermal shut off with a multimeter? but the spark from vent is strange? are u saying the venting into the wall hole is sparking with the lint goes as it exits the dryer? as for the squeaking could have been bearings or even the rollers, etc but that would not cause a sparking to take effect? unless u mean its sparking from the terminal block where power cord is connected?

You have a loose connection in the wall plug would be my first guess and is shorting out, you need to turn off the breaker going to the dryer and unplug it from the wall remove the screws holding the plug in the wall and check for loose wires and tighten if you find anything loose, or it could just be a bad plug that needs replaced. Good luck hope this helps.

One reason your seeing "really big and bright sparks" is because your dryer is wired with 240v!! Not something you want to mess with. Anytime you plan on working on a major appliance the very first step you should do is go to your panel box and turn off the breaker to that appliance. In your case the dryer. It's possible that when your trying to plug it back in that the dryer is still turned on. If that's not the case you may want to call a certified electrician to come out and take a look at it. Better to be safe than be sorry! 240 volts isn't something to play around with.

loose connection on the 220 plug in the wall ....go to electrical panel in your home and turn off both breakers to the dryer...this could cause a fire...call an electrician for repair

when you look at the terminal block there is 3 terminals right(red) center (white) left is(black) the other is common hook it to frame there should be a screw to attach it to . / if you hooked it up wrong the first time you may have electrical damage .. x your fingers. mm . some times the plug at the wall has been installed improperly. ck it .. mm good luck .

you most likely have a loose wire inside that wall outlet. use an extension cord to plug your dryer into another outlet that you know works properly and see it your dryer will work on that power source. If it does, just replace the receptacle in that wall outlet. If the dryer still wont run, then you know you have a problem with the dryer itself. If that is the case get back and I can talk you through solving that problem also.

Classic of a clogged vent to the outside, Air out back of dryer should be same outside. Dryer will get hot and take to long to dry clothes with a clogged vent. Pls leave a FIXYA rating.

your vent is plugged or the dryer is too close to the wall put unit on air only and go outside check for air if none come back indoors and gently pull the dryer away from the wall then go back outside to recheck air flow should have improve if not the lint screen housing is plugged

Well, the breaker has trip,but the microwave must have a short in it.Go turn turn back on and don't plug the microwave back into it to see if everything works.
