Bathroom heater inop

Bathroom ceiling heater isn't working. It's a nutone combo unit with the heater and fan each switched separately with receptacles part of the unit. Black wire to the working fan, red to the inop heater, common white. The heater works if I plug it into a wall outlet. I replaced the heater receptacle in the ceiling box - Still not working. With the breaker off, the heater switch read open both ways when switched. Compared it to the fan switch which read open/ short when switched.. Pulled the heater switch, it reads open/short when switched. Hmmm. Turned the breaker on, black to ground reads hot, black to red nothing, red to ground nothing. The red appears dedicated to switch the heater because there is only one red into the switch, not pigtailed to anything else and only one red coming into the ceiling box and it's a direct short between the two. What am I missing?

Welcome to the forums.

To eliminate a switch problem..... connect the red heater wire directly to the always live hot black wire.

Apparently, just the back hole connection of that switch was bad.

That's called a stab connection. There is a little clip that holds the wire connected and in place. You'd be much better off with a higher load item like that heater if you used the screw terminals on the switch.

Those stab connections are notorious for going bad.
