I've started using a Ryobi heatgun in my roasting setup after the old GMC one gave up. I've found with this the thermal cutout activates very early, which keeps the fan blowing but with no heating element. Sadly, thats destroying my chance of a decent roast. I plan to setup a desk fan blowing onto the heat gun and see if that helps, and maybe using an extension nozzle? Other than that, any other ideas?
