I replaced the thermal fuse a week ago and the customer tells me that it blew again. What is causing this to happen?
1. I replaced the dryer vent hose the last time that I was there.
2. I cleaned the inside of the dryer as well.
3. I checked the flappers outside and it is working.
Cleaned inside of the dryer
Checked flappers for operation. Ok
How long is the vent ? How many 90 degree and 45 degree fittings do you have ? If the outside vent flap is opening that is not 100% confirmation of proper air movement to eliminate thermal fuse from opening . If it is a short vent with no 90/45 degree fittings and you feel great air flow I would put on a cycle thermostat. If you have a long vent, pull out the dryer and put on a thermal fuse and put on the ProFlex Indoor Dryer Vent Kit for two weeks to verify it is a vent issue. This will bypass the vent completely and confirm you have no other issues after two weeks. Then either clean the vent or refer to a vent cleaning specialists. This is an easy way of process of elimination for $10.00 and you can keep it for future use of the same issue. See the link below for Proflex. Matt Ace technician
