Hi Kenny. Thanks for sending your question to us today. When multiple electrical issues like you’ve described exist, there are two distinct possibilities. First, you either have an exposed wire that is creating a rather serious short, or you have several sensor, fuses or relays that are not working properly. The first thing I’d do is check the fuse and relay that powers your heater. If it’s not damaged, then you likely have a pretty serious electrical gremlin that would require an electrical inspection to isolate.
