Started troubleshooting the Trauslen freezer through establishing the evaporator compartment and determined the evaporator coil iced up. Turned the unit into defrost and determined the heating factors now no longer getting hot. Checked the amperage of the factors and no amps being drawn.
Applied direct electricity to heater relay to shut transfer and warmers began out running, pulling 4.three amps. Found the controller become now no longer sending electricity to the heater relay. Went via parameters at the controller and determined the evaporator sensor t
emperature showing become absolutely off the chart. Checked the resistance of the sensor and it did now no longer fit the temperature / resistance chart with inside the provider manual. Determined the evaporator coil sensor become horrific which become inflicting the unit now no longer to go into the defrost cycle. De-iced the evaporator coil and changed the evaporator sensor. commercial fridge parts
Placed stubby gauges on provider ports and checked the refrigerant charge. Both excessive and occasional aspect pressures strolling normal. I showed the coil sensor temperature in controller to make sure it become analyzing efficaciously and it become.
Also determined a few controller parameters were changed. Spoke with a Traulsen tech guide character to run via controller settings and set them again to manufacturing facility defaults. Tested the freezer’s defrost and operation one final time to verify the whole lot become running adore it should. Watched the container pull down and finished job. traulsen refrigeration parts
