You may be able to obtain a service manual for the Creda T620CW dryer by contacting the manufacturer or a local appliance repair service. They may be able to provide you with a copy of the manual or direct you to a reliable source. Alternatively, you can search for the manual online through websites that specialize in appliance manuals or user forums where others may have shared the manual.
There is no definitive instructions to so this. Normally, go around to the back and remove screws or press catches to loosen and remove the top. Remove screws at the front kickplate. Pull the door and front forward, remembering that there are wires attached. Replace the latch and rebuild.

we had a similar problem happen with our Hampton Bay Renaissance fan. It turns out that the warranty does not cover this by the way. The lifetime warranty you refer to is only on the fan motor. This is common with most fan manufacturers- just wanted to let you know about this because I think your interpretation of the warranty is wrong.
This fan is really hard to find and so are the parts for it. I would recommend trying to call Home Depot where you bought it or call the Hampton Bay customer support phone number. You're likely going to have to go through one of those mediums. I feel that the second thing (calling technical support for Hampton Bay) will probably connect you to Home Depot too because Hampton Bay is a house brand of Home Depot.
We were able to find the phone numbers we needed here:

They always screech when the belt slips. There are usually only 2 reasons this happens.
The drum slides at the lower front are worn out and creating too much friction.
Or
The rear drum bearing has worn out, and again too much friction.

The screws and spacers for the device are lost. However, the mounting hardware could easily be replaced by three screws and corresponding plastic bushings/spacers. Unfortunately, I could not find any information about a fuse for this device. If you're still experiencing issues, I recommend contacting the manufacturer or a certified repair technician.
