I have an 8 year old Bonaire VSM60/65 and the control box is fried. Supposedly a common problem. I have been quoted $1000 to replace and fit. I can buy an entire new VSM65 for that price, or used one for $300 and so I’m trying to find out compatibility of the control boxes old vs new so I can get electrician to fit. Is this something you can help with or do I need to contact Bonaire directly? Can you suggest what the price of just a new control box would be?
