I have a kitchenaid dryer that worked fine all day and then my last load to be dryed no heat not at all

Sounds suspiciously like worn support roller shaft bearings. When they get bad sometimes the rollers just wobble on the shaft and eventually, if the dryer isn't shut down and repair quickly, the shafts will become severely worn and will need to be replaced as well as the rollers. It will most likely have to be disassembled before a good estimate can be made.

Have you cleaned the blower vent pipes lately. Sounds like the vents may be stopped up with lint and it got too hot. Clean vents and where the fan blade is to be sure the fan can turn. I have found everything you can think of in the blower housing that would keep the fan from turning.Be sure and get the lint out they all have some. As far as the heat not working check all thermastats , the thermal fuse on blower box and thermal cutoff usely on the heater box. and the heater coil also check with an ohmeter from heater coil connections to the metal box it's in ,the coil could be grounded inside the box.
Hope this helps.

Hi, If you have a gas dryer.
The most common problem with a gas and no heat is the ignitor going bad...

Here is a tip that I wrote about that problem...

Hi,

Make sure front of dryer is not blocked, air flow is needed to dry.Check that the lint filter and exhaust duct is clean.

Check the blown fuses and home’s circuit breaker tripped. Dryer use 2 household Fuses or a circuit breakers, If one is blown, the dryer may still operate but not heat. Alternatively, the dryer may heat, but it may not heat up as hot as it should. Replace the Fuses or reset the circuit breaker.


Another common cause of a dryer failing to heat is a faulty Heating Element. You will need to replace it.


Good Luck and have a nice day.
Rating the solution is highly appreciated.

replace the gas valve coils. they sit right on top of the gas valve. they are black and round, and clide down over a shaft. remove screw from plate holding them, and slide them up and off, replace, and it will run....turn gas off while working on unit:)

the vent in your house may be stop up in the wall.

The operating coils get hot and quit. They only cost 20 bucks. Read more about it here:
Gas dryer works then quits then works some more

Sounds like the heating element or coil is out, but it could also be the board to. At any rate, if your not getting any heat what so ever, its more than likely electrical and its best to take it in. If it gets some kind of heat, then you might try cleaning out your dryer vents really good, and also in the dryer. Hope this helps.

any number of things actually, lets start with the basics, does it start at all just not dry???with a meter you can troubleshoot most problems right behind unit taking off back panel and checking the thermostats for continuity, the heater can also be checked right there , any one not having good continuity needs to replaced, perhaps after 3 loads it got too hot and overheated a thermo or the heating coil went bad
