Refrigerator needed troubleshooting as it had been previousl worked on by another company and problem wasn't fixed. Talked to Rob and he had an idea of what might be going on. He brought Refrigerator tech and himself out to repair fridge. They were determined to find problem. They had a spare fan blade with proper rotation for my evap fan.Cant say enough great things about this service call!!! I was told be previous tech, different company , to buy another fridge. This Whirlpool is 3 and a half years old. 152 bill and they fixed my fridge. Thank you very much. Will call this company everytime.
