"Customer said about a week later the fresh food section start warming up. The customer remove the panel and found the evaporator was frosted over again. I test the temp sensor, it did test ok but I replaced it anyways. The heater is testing good every time. I put it into defrost mode and the heater was drawing 3.6 amps. In the fault mode the light indicating 9 was on. According to the tech sheet that is a faulty defrost sensor. I do get 5 volts dc to the sensor. If the issue continues it has to be a main wire issue in the cabinet and its not repairable."

The complaint was the freezer evaporator is frosting up again. The customer had to manually defrost it. Last visit it went into defrost and the heater came on. I had notes that if it happen again to order the main control. Today I replaced the main control board.

This is a built in refrigerator and Wright Hennepin does not cover built in so nothing is covered on it. The customer complaint is the fresh food is not getting to set temp and the over temp alarm is going off. The freezer is set to minus 10 and the fresh food was on max coldest setting. The freezer showed minus 10 and the fresh food showed 51. I found the cold air return was blocked so the fresh food was not getting good air flow in the section. There is frost and ice build up only on the right side of the evaporator and in the air ducts. A door may have been left ajar and allowed warm air to leak in and cause the frost and ice build up. The evaporator has normal amount of frost. The evaporator fan is working fine. The defrost is working fine. After I cleared the supply and return duct the air flow is better. Theirs a small chance it has a sealed system issue but as of today the evaporator looked good. Sometimes ice accumulating on the right side of the evaporator can be caused by a low charge which is caused by a leak in the sealed system.

Had E15 and E25 error. Found glass stuck in the drain pump. Made sure drain line was clean. Sump is clean. Part of sump was out. I reinstalled that. Water was on flood pan. Dried that out. Customer said their dishwasher overfilled when it couldnt drain. Runs and drains great now.

Installed new drain pump and wasnt turning on found that it wasnt getting enough voltage to the pump was only getting 15 volts to the pump which should be close to 120. Ordered new control board W10854220 board from Dey ; ordrd 1 W10854220 (Board)
