No heat to dryer...it is an electric dryer. Power is good. How can I troubleshoot heating element or thermal fuse??

I am having the same issue. No heat at all. I've used the manual and followed the instructions to use white vinegar to clean the sensors inside the dryer. Power works but it blows cold air. I've tested it on timed cycle and made sure I'm using the heated dry and not air fluff.

There is a small red button on the high limit thermostat that's connected to the heater, when I opened the back of the unit I was able to push it and it seemed to click slightly. I thought this may have solved the issue but after testing again still no heat. The red button doesn't pop up again.

My next step is to try and replace the very inexpensive fuses in the fuse box and see if that has any change although I doubt it considering the entire front panel is working fine.

I'm guessing the heater AP2805474 needs to be replaced but I'm not 100% sure. Any advice?

Funny, that is the same case w/ my Bosch dryer currently. I have tried all you have as well, just not pulled the back off of it. Mine is currently about two months out of warranty and I have only had it 1 yr & 1/2 months.

I am having almost the same issue with my Bosch Axxis WTA 3510 UC/13 dryer. Have you reached any solution? what have you done so far? please post if you have any advice

quick update. The heat is working again. How? I'm not exactly sure. Maybe pushing the red button on the back fixed it. I would recommend giving it a try.

Resetting the button in my dryer did not work. Any other ideas of what it might be? How do I check what part is faulty?

We have had this issue for the past couple years and the solution has been to clean the heating element in the back of the dryer. The element clogs up with lint and some of the lint shows evidence of burning. There are two sensors here and and they shut down the element. Safe guard system. After carefully cleaning out the lint and reinstalling the the heating element the dryer works like it was new.
My issue with this, is that Bosch's lint collection system design is extremely poor. Lint should not be bypassing the filter and getting into places it should not be! If you take on the challenge of opening up the dryer you will be shocked by how much lint has accumulated through out the rest of the dryer. We now clean the dryer out completely every 6 month's. Which means opening all the panels. Top/ back & sides. The heating element on the back of the dryer is easy to take off. A couple torx screws (6 to 8). You need to take the cover off the box that protects the heating element, these are tabs that fold over. When you unfold the tabs the heating element will fall out so be very careful. (This should go with out saying, but I will say it anyways, unplug the dryer before attempting the cleaning) To clean the elements we use a tooth brush. Take care to not damage the elements and they "should not touch each other". We are a family of 4 and laundry is done once a week and the lint screen is cleaned after each load. We took pictures to send to Bosch and have not completed our e-mail. I personally believe this is a design issue that Bosch has missed. Unfortunately the fix is major and therefore nothing will be done. My faith in Bosch and the quality, we as consumers have come to expect was missed in the development of this dryer. My biggest concern is a fire from the lint blockage on the heating element, safe guards or not, the risk is there.

Discovered that the little flapper door where the dryer vent goes outside was stuck closed. That obviously tripped the thermal breaker.

Thoroughly cleaned the vent flap outside to free the flapper door, cleaned the vent tube, and gave the lint filter screen a good soaking in a soapy bath and scrubbed it clean.

UNPLUGGED THE DRYER. Took the access panel off the back of the dryer and gave it a good vacuuming, removed the heating element unit, carefully pried the little tabs up and pulled it apart. Gave the heating coils a good (but gently) vacuuming with the brush attachment. Reassembled/reattached the heating element and pressed the red reset button.

Replaced the access panel, plugged it back in and VOILA!! Heat!

Thank you all very much!

1992 Chevy Lumina. I replaced the thermostat and the core is not leaking. If you have any ideas to what I can do to get heat I'd appreciate it.
