About four years ago, I completed the restoration of my Harrison fresh air heater to include the 12 volt motor, potentiometer, and DC motor controller. Twice now (in four years) it has blown the 10 amp fuse. Has anyone else had a problem like this? It doesn't have much run time on it and after the fuse is replaced it is fine, until it isn't. I'm reluctant to put a bigger fuse in the system, so I thought I'd run this by you. I see in your schematic the 12 volt DC motor controller is rated up to 20 amps. I'm just wondering if I have a component problem or an under fused circuit.
Let me know your thoughts, thanks!
