When the furnace was turned on, the blower motor would work for a few seconds, then stop, then turn back on after three seconds, shut off again, and so on. Our technician checked power when the fan motor was on - it was not continuous. This was an indication that power was not continuous from the white rodgers 50a50-241 control board so he decided to replace it. But after he replaced the white rodgers 50a50-241 for its analogue white rodgers 50A55-843, the problem remained. The tech tried switching the black power wire (high speed) of the blower motor with the orange one (medium-low speed). When he did that, the blower motor started working, but when he connected the black power wire back, the amana furnace blower motor 20046612s wasn’t working again. After the tech replaced the 20046612s motor for its new analogue, the Amana furnace guic140cx50 started working perfectly fine, and the customer was glad to have his furnace up and running again.

This customer’s Nu-Vu UB-5/10 Bread Oven stopped working. At first glance, everything seemed to be working fine, but with a more thorough check the tech noticed that the control board was not getting 208V power. He had to pull up the the whole power supply diagram before doing any further work. Once he was familiar with that, he started checking the wires and was finally able to find the disconnection and fix it. Most likely, one of the wires was simply defective.
We got a call for commercial order from the Indian Street Cafe. They needed urgent help with their TurboAir fridge that had stopped working properly. During the diagnostic our technician noticed a big chunk of ice that has accumulated on the evaporator coil. Apparently the seal of the fridge was not airtight anymore. Replacing the door gaskets and the defrost sensor fixed the defrosting problem of TurboAir M3R47-2 fridge.
Whenever the customer was trying to get some water from the water dispenser of his GE fridge, there was scary loud humming noise which seemed to be coming from where the water filter is connected. Our tech decided to try replacing the Refrigerator Water Filter Head Assembly Part #: WR17X11894 - and it fixed the problem. With the new water filter assembly the humming noise during water dispensing has stopped.
