An old fridge without the motherboard can work almost as well and tends to be much more durable. 

So I authorized the tenant to call in an appliance repair co, they collected a $100 one time charge, and said the mother board controller needs replacing and it would be like $500 and there would be a one week wait. 

I've had thermostats successfully repaired, and I just replaced the motherboard in my own fancy Samsung.

When a roof leaks, I replace instead of patching, when a furnace fan or mother board fails, I replace instead of swapping out.

The new dealer might be able to bring system to default settings - not likely but maybe.Otherwise, dealer will need to replace motherboard, keypads/consoles and reprogram system.

When the parts break, they are cheaper to repair and replace than a motherboard would be for a washer with digital programming buttons (appx $50 for parts vs $900).Cheers,Melissa

Shorted out the motherboard on the boiler...which I was told shorted out 2 other parts.I was told that the polarity was set up reversed when the boiler was installed...when it was changed at the circuit box but not the boiler the parts "fried"

Will a $550 roof repair  (if I ever have one) or an appliance repair (motherboard) be considered a restoration or betterment?  

All kitchen appliances (did not have a refrigerator) and some staging stolen in the first one, along with vandalized furnace (what did the mother board do to deserve it?)
