What does it mean when the red light is on on my cadet in-wall heater? What can be done?
The light is actually to tell you that the safety has been activated. This is usually an indication that the heater is dirty and needs to be cleaned. Turn the heater off at the breaker and take the grill off. Use a hairdryer or a shopvac on the exhaust side and blow the heater clean. If this doesn't fix it the the heater will need to be replaced. The light indicates that you have an "X" model heater.
