Thermistors Evaporator Thermistor Thermistors are used for various temperature readings. If the evaporator thermistor fails, the unit will rely on a Thermistors provid e reliable temperature readings preset defrost timer during defrost cycles. The unit will using a resistance which varies based on surrounding otherwise operate normally. Refer to defrost section. temperatures. If a faulty thermistor is suspected it may be tested using an accurate ohmmeter.
Defrost This unit defrosts every 4 hours of compressor runtime for 45 minutes. If you have verified that the unit does not have an ambient air leak, utilize the Control Operation - Service section and adjust unit to defrost every 3 hours for 60 minutes. Also, adjust the #2 thermistor to -4 instead of 0.
Remove Fan and Cover 6. Remove insulating foam from refrigerant line passthrough hole as needed to gain clearance for fan plug. CONVECTION COOLING This unit is equipped with an advanced convection cooling system. Convection cooling stabilizes cabinet temperature, cools product faster and increases energy efficiency. 7. Remove internal shelving. 8. Remove evaporator cover screws. 9.
NOTICE Fan must be oriented to pull air in through lower evaporator cover vents and push air out at fan mounting location. 13. Installation is the reverse of removal. 14. Care must be taken to assure the bottom of the evaporator cover is reinstalled behind the front edge of the train trough. 15. Use sealant gum to seal any openings at rear of unit before replacing rear cover. 16. Reinstall unit taking care to level, space and secure as found.
