Question about Pentair Minimax NT Heater
Heater will not fire up. Error messgae "EO3" (Thermal Fuse Open). How to Fix? Mike Daley
The thermal fuse is a cheap one use part. It is located inside the front of the cabinet, right in the middle. It is about 4 inches long, and looks like a black rubber tube with a wire on each side of it. This is something that you can replace yourself. Parts are easy to find for this model.
When the part is replaced , make sure you take the time to find out why the part failed. The thermal fuse is meant to be a safeguard to ensure that the flames are not out of control. Sometimes they do just fail, by typically there is a reason when they go out. Make sure gas and air supply is correct, and the burner tray is unobstructed. If there has been high wind in your area, this could have been the cause of the failure.
Part number from manufacturer is: 075173 and should cost between 15-20 dollars US.
