Thermal fuse / vent ducting
I have the Maytag MEDEX655DW1, 2 years old. Dryer quit running and I found the thermal fuse was blown; replaced it, hit start and it ran. I immediately stopped the unit and hook back the vent duct and started to dry a load. When I came back to check the top of the unit was scorching hot so I turned the unit off. I unplugged and unhooked the unit from the vent duct and cleaned / vacuumed all lent throughout. I then ran the unit unhooked from the vent for about 30 minutes on high heat measuring the temperature from the center of the exhaust. The temp built to 142 degrees and I was satisfied so I hooked vent duct back up and I ran a load on air fluff. The temperature had heat in it.
The unit is installed on a interior wall about 8’ from a exterior wall. The duct flows through the floor and is the flexible foil type and does not reach the exterior of the house or have a cover on the end under the house. I ran a brush through the vent from the inside and saw it reach the other end. I plan on replacing the duct today but my question is would that be the reason for the overheating and why would it heat up on air fluff?
…after all that I decided to stop all drying till I replace vent duct and test again then my wife decided to run a load on high heat and the fuse blew again…
