Bosch Dryer Model # WTMC332BUS/06 not starting after cleaning

Hoping someone on this forum might have some insight. Given the current state of the world, trying to DIY this repair rather than have someone in our tight house. 

 Our Bosch Dryer model # WTMC332BUS/06 has been great for us. I think we have owned it 11-12 years and its still a work horse for our family of 5. 

 

That said, about 2 years ago my wife smelled a burning smell and understandably was freaked out. I did a complete cleaning of the lint filter and lint filter box snaking it. We ended up having a repairman out and I'm not sure what he did other than I think he pulled some lint out from under the drum. 

 

Four days ago we were getting the same burning smell. Given the current state of isolation I figured this was a good time to tear the whole dryer open and clean everything. In doing so, I did the following;

- Removed lint filter and cleaned. 

- Fabricated a thin hose extension for my shop vac and vacuumed the entire lint box. 

- Removed the top cover and rear cover of the dryer exposing the back of the drum and underneath of the dryer. 

- Vaccuumed lots of lint from under the drum, around the belt pully assembly and generally the whole bottom side of the dryer. 

- I disconnected the heating element duct from the back side of the drum and used the same fabricated hose to vacuum up inside the rear of the drum. In doing so the drum did shift slightly back, but I was able to move it back forward and it appears to turn freely as it did. 

- On our model, the heating element duct soft of pivots or hinges down once disconnected allowing me to see the heating element. It also had several large balls of lint including one that was charred. Vaccummed and removed those as well. 

 

In doing all of this, I did not disconnect any electrical leads. This was simply a disassembly of the structure to clean and everything was put back together as it was. 

 

When I was done reassembling and had plugged back in, the dryer had power and when put to a setting and hitting the start button, it's not turning on. 

I am getting a first smaller "click" which I believe is the door safety switch and then a secondary "harder" or louder click. I now have the dryer dissassembled again. The secondary click appears to be coming from the back of the drum although I can't see anything electric there other than the plug. The clicking is not coming from the plug. 

 

Pictures below show the disassembled state. 

 

I would appreciate any insight this forum has as to things to look or check for. Much appreciated - stay safe everyone!

Investigated the second "click" further and it appears to be this relay/fuse coming in off of the power cord (shown in picture #2).  Does anyone know what this could be? I'm wondering if the relay could have been damaged turning the back of the dryer up on top of the machine while working on it?

There is a black plunger on the belt switch that you push in to reset after taking the belt off. Push it from the left toward the right. Best accessed from the rear.

@Scottekarate, delayed thank you for your input. The belt switch reset did the trick! 

 

Simple and easy, just the way it should be. 

 

Much appreciated!

I'm happy to hear it. Thank you for letting us know. @BostonContractor
