Pike hunter. If its just the thermostat, change it. Maytag fridges are good fridges. Made by americain admiral or Whirlpool depending on the year. Stay clear of samsung and lg fridges. Parts are hard to get, and expensive. When you buy a fridge, you want it to last longer than the warranty, so think about ease of repair. all new fridges are made with underpowered compressors.They burn out in less than 2-3 years. I see it everyday.
If it was mine, i would fix it for sure. Controls are an easy fix.I know, becase i have 30 years in the appliance parts bussiness, and own my own parts company. FIX IT, or if you have your mind made up to buy, go whirlpool,(kitchenaid,inglis,roper) or get another maytag.Sears are usually made by lg, samsung or frigidaire.PM me if you have any questions
