First of all you guys are awesome ; I ve had a local appliance company working for 3 months trying to fix my frig. Every time they came out they had the wrong part . So I have been getting out the old blow dryer twice a week to defrost my appliance . I finally just gave up and told them i was just going to get a new refrigerator . Fortunately i looked at your web first ! i typed in the model # and looked up the controller ,here is where the problem was , the part called out by whirlpool isn't what is in my fridge even though the controller in my fridge is the original . so i just went on your web page and looked at all whirlpool Defrost Controllers and like the second one pictured was the one i needed. Even though it is listed none compatible with my machine i was able to zoom in on your web page and compare every circuit ,connector ,voltages listed, it was the exact same part .You guys must have some crazy magic because i ordered the part @ 4pm and the next day @ 2pm the part is at my house. it took 5 min to put in and it has been working great . Your site saved me a lot of money . I should have gone to you sooner. Thanks
