Hi, My three year old Maytag bottom freezer won't cool top or bottom. Everything thawed out about a month ago, threw it all away, fridge starting working again. Bought new food and two weeks later same thing. Cleaned out fridge and started over and now again last night. Spent the late night hours and wee hours this a.m. to clean out fridge. When it runs it runs great. But then after a couple of weeks it quits working again. I vacuumed off the condenser coils under the fridge and it doesn't seem to help. There is a "too warm alarm" that never came on. Lights work, but I feel like the non-working temp alarm may indicate a malfunctioning mother board. Any help will be appreciated as I am embarassingly unemployed and broke.
