Absolutely replace that thermal fuse, personaly, I think its bad advice to suggest to people to bypass something like this because more often than not they will afterwards see it working and just leave it bypassed rather than ordering the part or while waiting for the part and not understand the urgency of replacing this particular part.
This part in particular is pretty much the only thing standing between you and your house burning down. Its a safety part thats only going to go bad if a safety problem exists.
You less likely have a thermostat thats not shutting off allowing it to overheat to the point that this thermal fuse has blown, or you more likely have lint blocking the air flow somewhere between the burner and the exhouast at the outside of your house.
This will absolutely lead to a fire if untreated, as well as exhaust gas to accumulate inside the house instead of being properly vented out. You should refuse the tempatation of trying to use this dryer with that part on particular bypassed even while waiting for the part to come in and time to replace it. You also need to solve the less obvious problem behind why this fuse blew in the first place. | 
Roper GAS dryer won't heat 
. I remember seeing the igniter glow at times even when the gas supply was empty. 
we're heating. I suppose I need to order one of thos thermal gadgets huh? I bought my igniter from Parts Select and will do the same with the Thermal fuse.
