Ms Kelly

I am have the SAME EXACT issue with my 2007 Hot Springs Envoy. I replaced a GFI early Spring.....replaced the heater in the Summer....now still blinking red power light after a while powered up. Never seems to reach...or just reaches the set temp ...then trips. Techs are raping me with services calls only for them to finally tell me its MAY BE the Hi Limit Switch OR the Circulation Pump. I'm not paying these guys to come back another 3 or 4 times at $150.00 a pop. Anyone have any ideas what the problem maybe? Kelly G. - Johnson City, NY
