Defrost termination temperature sensor.

Replaces cpc defrost termination temperature sensor part numbers 501 1135 501 1127 replaces parker micro thermo technologies defrost termination temperature sensor part number 023 0072 brass pipe mount sensor bulb 20ft orange zip cord cable 10k type 2. The interior temperature may rise 10 20 f during the defrost. After a run period of approximately 6 hours the evaporator coil will be frosted and require a defrost. Of 7 c 45 f.

Four defrost cycles per day are programmed at the factory 4 a m 10 a m 4 p m and 10 p m. If your customer complains of icing on the floor don t increase the number of defrost cycles or the termination temperature. Adjustable temperature termination controls allow for better tweaking of the system to prevent this condition. And what you need to sense is coil temperature.

Defrost controlled by rts al61 al61 al61 heaters failure improper current draw from heater turn on or off. 0 125 because this item is not stocked in our warehouse processing transit times and stock availability will vary. If the temperature sensor or thermostat isn t working correctly it will still go back to refrigerating once the time is complete. When the defrost sensor trips it shut off power to the defrost heater.

The refrigerator defrost sensor also known as the defrost bi metal termination thermostat trips when it detects that the temperature of the evaporator is getting hot enough that it might overheat. If you need your items by a certain date please contact us prior to placing your order. The freezer defrost sensor also known as the defrost bi metal or defrost termination thermostat is next to the evaporator. Instead lower the termination temperature or move the termination sensor on the coil.

If the time is set way too long for defrost the temperature termination will stop the defrost and send it into refrigeration mode before the product gets too warm. Your still sensing temperature. It may be necessary to change the defrost cycle times to fit your work schedule.

Al60 al60 al60 defrost termination sensor failure dts htt open or dts fails to open afer 2 hrs of defrost dts fails to close after 1 5 hrs of comp. The evaporator coil cannot go above 32ºf so long as there is still ice in that area so it stands to reason that if heaters are running on the coil and the coil is still at 32ºf or lower then there is still ice. Instead of the use of a klixon which is attached to the coil your using an anolog temperature sensor to a cpc input. Omnitemp 37t32 defrost termination switch.

The idea behind defrost termination is to know the coil temperature.
