Fridge...again

The repairman came yesterday and after he looked at it said that I had to plug it into a grounded plug. Guess what? None of my plugs are grounded. He checked all of the plugs in the kitchen area and said that I would either have to have an electrician or get a new fridge. He said that the fridge would work for awhile but there was a cycle that the computer screen on the front goes through that has to have a grounded plug. I am electronically challenged so of course I called Nana. She looked into and said that I would probably gave to have an electrician. I spoke with one but he can't get out until the end of next week. The fridge is working for now and I'm just hoping it makes it until he can come out. I think that they should have mentioned that when we bought the fridge, although it is in the manual which we didn't read until now.
