TRANE TECHNOLOGIES KIT19795 Defrost Coil Sensor Kit
Product Information
Product Name: Defrost Coil Sensor Kit
Model: KIT19795
Compatibility: Used on all HP models except Side Discharge models
Manufacturer: N/A
Product Usage Instructions
- Inspect the package: Unpack all components of the kit and carefully check for any shipping damage. If any damage is found, report it immediately and make a claim against the transportation company.
- Check for missing components: Ensure that all components are present in the package. If any components are missing, report it to your supplier and replace them with authorized components only.
- Coil Sensor Installation:
- To remove the existing clip, firmly hold the sensor base with both hands. Firmly press with both thumbs on the open end of the clip and push towards the sensor bulb.
- To replace with the 3/8 clip, line up the clip notches to the sensor base and follow the steps in reverse.
- Relocating the Coil Sensor:
- Use the troubleshooting flowchart provided to identify the new placement of the coil sensor.
- Disconnect high voltage power from the outdoor unit.
- Remove the power wire for the outdoor fan motor (refer to figure 1 for wire location).
- Safely secure and insulate the connector of the black power wire removed from DFC.
- Reapply power to the outdoor unit and call for heating. Note: The unit will be running without the fan.
- If no ice band or short defrost is observed, no further action is required.
- If ice band or short defrost is observed, relocate and secure the CBS with the new 3/8 coil clip to the coldest circuit.
- Measure the inlet temperature of each refrigerant circuit.
- While the system is operating, observe each refrigerant circuit.
- Disconnect power and reinstall the power lead for the OD fan.
- Apply power and check for heating operation.
Please ensure that all installation and troubleshooting steps are performed by qualified personnel and in compliance with national, state, and local codes. Failure to follow safety precautions may result in property damage, personal injury, or death.
ALL phases of this installation must comply with NATIONAL, STATE AND LOCAL

Safety Considerations
WARNING!
Only qualified personnel should install and service the equipment. The
installation, starting up, and servicing of heating, ventilating, and air-
conditioning equipment can be hazardous and requires specific knowledge and
training. Improperly installed, adjusted or altered equipment by an
unqualified person could result in death or serious injury. When working on
the equipment, observe all precautions in the literature and on the tags,
stickers, and labels that are attached to the equipment.
WARNING
HAZARDOUS VOLTAGE!
- Failure to follow this Warning could result in property damage, severe personal injury, or death.
- Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized.
Inspection
- Unpack all components of the kit.
- Check carefully for any shipping damage. If any damage is found, this must be reported immediately and a claim made against the transportation company.
- Check to be sure all components are in the package. Any missing components should be reported to your supplier at once and replaced with authorized components only.
General Information
It is normal to have variations in feeding of the outdoor refrigerant circuits. In some applications it is normal to see this in the form of frost banding. The recommended solution in these situations is to relocate the coil sensor to another circuit.
- Before relocating the coil sensor, verify the following:
- refrigerant charge
- indoor air performance and
- air circulation around the outdoor unit
Steps in this document will aid in the identification of which circuit might be best in the relocation of the coil sensor.

Installation
- To remove the clip, firmly hold sensor base with both hands. Firmly press with both thumbs on the open end of the clip and push towards the sensor bulb.
- To replace with the 3/8 clip, line up the clip notches to the sensor base and follow steps in reverse.
- Use the steps in the troubleshooting flowchart on the next page to identify the new placement of the coil sensor.
Below are before and after examples of sensors that have been relocated on Trane, American Standard and Runtru heat pumps. These pictures are for reference only. Follow troubleshooting tree to find best location for coil sensor. If ice banding is found on side discharge models, contact your local distributor for further troubleshooting assistance.
