When I have gotten home the last couple of days the tub is running with the air blower going and the contral panel flashes OH. When I turn off the blower the temp has dropped around ten degrees both times. Also have noticed that the blower comes on a couple of times when the pump comes on by itself to filter the water the blower motor is a new one I had to replace it about a month ago. I got the tub with a cracked main 1.5 inch line because it wasnt winterized right. I was told that the blower hasn't worked for a couple of years. It sounds like there might be something wrong with the control pack in the tub. Please help this tub has been trouble since I got it. I also have to still replace the cover it is the OEM and weights about 85 lbs right now. Might just drain and not mess with. Thanks in advance with the help.

Last night I turned it down 1 degree to 100. The tub is wired for 220v. The blower and is 110v any help would be great. Thanks

Update: I have had the temp set at 100 for a couple of days with now problems. The spa pack is a balboa 2000 valve. The circuit board number is 54161. It looks like it has a pressur switch with the HI-limit and temp sensor as the same that part number is 30382. When I got it from my my family they lived in the contry with farm fields all around so mice have made there way into the spa pack. Here a couple of pics. Could it be the temp sensor or a circuit board. I dont really want to spend $200-300 on a board if it wornt fix it. I am thinking of tring the temp sensor it is a lot cheaper to just try please help I want to get this thing working. I have had problems with small leaks since I have had it. I have fixed the leaks now but it also needs a cover. Just want to get it working right to enjoy. Dont now about anyone else but working on my tub isnt as much fun as relaxing in it.

Nevermind after a week of checking this I was able to fix it dont need any help.
