The best advice is to call a qualified HVAC company and have them help with your issue. We can't give you DIY advice and dealing with high temperature steam and electricity is something better left to a good pro, the operative word there being 'good'. As in 'good' luck with your issue.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
