hello there,
i have Jensen 24a wood furnace and it needs a new switch. the manual calls it the "rheostat", but it's like any other variable speed controller with two wires. I bought two inexpensive ones off ebay only to find they are labeled as dimmer switches though they were advertised for wood stove blowers/fans. this switch is to control the draft/stoker fan and neither of the two will activate it. so, I set about testing them with my ohm meter and I get no continuity or resistance with the switch turned on. I thought maybe they're just lemons, but I then tested a brand new ceiling fan wall switch and same thing....no continuity. I have some practical working knowledge and experience with installing and troubleshooting electrical systems with 120/240 and 12v, so I know how to use my meter. I just don't understand why I'm not getting continuity. are these type switches not like any other type switches? seems unlikely all three of these would be bad
thanks, matthew
ps. I realize the reason for the stoker not activating might be due to something else, but want to start by understanding what I'm seeing with the switches
