When our technician came out for diagnostic, the 3 year old Samsung RF263BEAESR refrigerator was at 0F on the freezer side, and 48F on the fresh food side. The self-diagnose setting showed errors 22 and 25, which are indicators for issues with evaporator fan motor and defrost problems. The fan in the fresh food side was not working. The tech also noticed pieces of ice on the vent openings of the evaporator coil. When he removed the top from the fresh food side evaporator coil, he saw ice and snow which were blocking the air from the evaporator fan motor. After he defrosted this mess, he found the real cause of the issues with this fridge - a defective thermal sensor, which instead of the usual 10kOhms was showing around 70-80kOhms of resistance. The repair of the Samsung RF263BEAESR refrigerator was complete when the tech replaced the thermal sensor - the temperature in the fresh food section of the fridge started going down back to normal.

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.
