Since this happens repeatedly, with different dryers, it has to be something with the house, and that something has the potential to be a fire hazard. Please get a licensed electrician into your house asap, to check things out. My whole house surge protector is outside and connected somewhere by the meter, it doesnt interfere with my indoor electric. Had the same thing at the last house, where it was outside. Both were put in by the electric company, themselves. Another thought is, are you using the same cord, from dryer to dryer? It could be the dryer cord itself, if you have been doing that. Either way, something is shorting out and causing the dryer to go out, and could be a fire hazard.

How did the handyman test the receptacles? If he used a tester with just indicator lights, then he didn't check for overvoltage. Is this the only appliance or light which fails in this manner? Are there any other things on the same circuit? I assume it's a 220 volt dryer, so it should be on its own circuit.

My story. Old neighborhood wires from tall pole enter a box then wires connect to breaker box. Of course one eventually thinks bad breaker. Why else would an appliance keep burning out. Nooooo Wires from tall pole were deteriorated inside their box. on my house. Electric company cut the wires into house so we wouldn't burn. No electricity in the house and a two day fix. The company that did fix and replace outside boxes and wires said that is a common problem. Something is seriously wrong in your house. Get a good electrical company and find out. (Hint from my city inspectors. Use a company that only does electrical. None of those big companies that fix it all)

You said the vent was clean and clear,check it again and check it good. Sound's like it's either clooging up or kinking. Of all things electrical,heating elements are far less sensitive to voltage drop or spike. If the house was experiencing either problem,motors would be the first to go and fridge compressor would be #1.

Not necessarily, Klem. Refrigerators and dryers are both on their own circuits with nothing else, or at least they should be. It could be something in just the circuit for the dryer. It wouldnt affect the frig.

"Amber Peters Withycombe: Our dryer vent/line is only about a foot long and goes straight out the wall - ie: no kinks, no clogs."

I assume "a foot long" refers to the (flex) ducting between the dryer and wall, and the distance from the wall to the outdoors is "straight" through the wall without taking further turns. A trick is that foot-length of ducting can be curved or kinked behind the dryer to varying extents depending on where the wall opening is positioned in relation to the dryer outlet. Can you get a photo of what's behind the dryer ... without moving the machine which would disturb the lay of the ducting?

My dryer is at a corner with the wall opening too close to the sidewall such that it does not directly mate to the dryer's exhaust outlet. I can't push the dryer into the wall to make them match-up so I have to set the dryer at an angle to lessen the offset. Otherwise the restriction is enough that the dryer triggers an airflow obstruction fault.

Excellent example of how easily kinks can be overlooked dadoes. Also good information when you point out duct can extend far beyond where flex ends at wall. The clog may very well be inside wall where duct take's a turn right,left,down or up.

cat_ky , I only addressed whole house system because "someone" Said.

I believe it's too early to hire an electrician out of fear the place might catch fire. If there's reason to panic about possible fire,it is 100 times more likly due to lint than an electrical mal-function. It has been my observation most people coming here with questions do so to avoid spending unneccessary money on pros if they can fix it themselves. Rarly is a problem more suited for diy than this one. It's only a matter of making sure a pipe isn't clogged with lint (something I've seen more times than I can recall) but over a period of decades I've never once saw a heating element burn out due to over/under current EXCEPT in the event of lightning strike that burned out lights,appliances and electronic equipment at same time. Based on what personal experience or ohm's law, lead;s you to believe op can't fix this,should throw in the towel and call an electrician? If you are going to waffle then try and invalidate me you at least owe an explaination of why.

My exhaust distance is "straight through the wall." I can reach into the hood from outside, through that short length of duct and touch the dryer's blower which is directly at the machine's exhaust outlet (unique to the brand/model I have, I've never seen any other dryer designed as such).

I've ran into several that turned inside wall to exhaust in soffit and occasionally roof. Folks complain when exhaust come's out onto patio. It's a poor arrangement but code in some places. I've retro-ed a couple because owner's dogs were attacking them. Fan blades often cake up and cause reduced flow not only at exhaust but inside drum. Appear's we might be talking to the wall at this point so more suggestions aren't needed.
