number(s) listed in the attachment to this letter.
This is a safety recall SECOND NOTICE under the National Traffic and Motor
Vehicle Safety Act. Failure to perform the inspection and installation work described in this
letter as soon as possible could result in property damage or personal injury.
The 12-volt wire harness, used for the fuel heat option within the affected TRUs, may
be exposed and missing heat shrink. The exposed, energized 12-volt wires can, under certain
conditions, lead to electrical arcing and possibly a fire.
If your authorized Carrier Transicold dealer has not contacted you to arrange an
inspection of all affected TRUs shown in the attachment to this letter, please reach out to
them to coordinate the inspection. The inspection and rework will be provided at no charge
to you. During that inspection, the dealer will straight cut any exposed wires in the harness,
apply new heat shrink for some wires, add a connector to the remaining wires, and remove a
fuse. The inspection and securing of an affected TRU’s 12-volt harness will take
approximately 1.5 hours.
Carrier Transicold dealers have also received a reminder that the defect is present, and
that the affected TR Us’ 12-volt harness should be inspected and reworked. If your Carrier
Transicold dealer has already completed this inspection and rework in accordance with this
reminder, no further action is required. If you are unsure whether this occurred, please confirm
with your dealer as soon as possible. If you believe you have previously completed the remedy
work described in this notification letter and such work was not covered by the manufacturer’s

Descriptive Information : The Supra S6, S7, S8, S9 and S10 (NDTP) models of diesel truck refrigeration unit (together, the “affected TRU”) are sold by Carrier Corporation’s Carrier Transicold Division (“Carrier”) and are designed and used to maintain the temperature of frozen and/or chilled products during on-road truck transport.
The affected TRUs come with a 12V wire harness to provide power for a fuel heater post-production add-on accessory.
Production Dates : JAN 01, 2016 – SEP 22, 2022
Description of Defect :
Description of the Defect : The 12-V wire harness of the affected TRUs contain live power and have been found to be exposed when not attached to the postproduction fuel heater accessory, with stripped wire ends and a missing protection heat shrink.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : The exposed, live wires in the 12V wire harness in the affected TRUs could
potentially ground or have intermittent connection with surrounding cut wires or other metal components, which could lead to electrical arcing and localized heat. Hot copper from the wire could ignite a flame which could propagate to components in the surrounding area. Description of the Cause : In the affected TRUs the wire harness is missing the heat shrink that protects Part 573 Safety Recall Report 22E-090 Page 2 Identification of Any Warning
that can Occur : the stripped wire ends, either as a result of not being installed by the supplier or falling off after production.
Visual inspection should clearly show the missing heat shrink in the area of concern on the wire harness. Involved Components : Component Name : NR Component Description : NR Component Part Number : NR Supplier Identification : Component Manufacturer
Name : Electrical Components International Address : 1 City Place Drive
Suite 450 St. Louis Missouri 63141
Country : United States Chronology :
On August 16, 2022, Carrier received notification of a thermal incident involving a Supra S6 TRU in Aurora, CO. On September 14, 2022, a field inspection was conducted, with an independent third-party fire investigator, into potential causes of the thermal event. On September 20, 2022, a production line inspection showed that the affected TRU’s wire harness was missing the heat shrinks, such that the exposed wires in the harness may come into contact with surrounding metal or other exposed wires. As a result, all shipments of affected TRUs were put on hold on September 22, 2022, and Carrier immediately began a careful analysis of the affected TRU’s wire harness to assess the potential product safety risk. To date there has been only the one thermal event related to this issue, and no other field reports of arcing. After much internal analysis and discussion with safety engineers, on October 20, 2022, Carrier determined that the issue presented a potential safety-related defect reportable to NHTSA under Part 573. That same business day, on October 20, 2022, Carrier filed this 573 Defect and Non-Compliance Report. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22E-090
Page 3
The information contained in this report was submitted pursuant to 49 CFR §573
Description of Remedy :
Description of Remedy Program : Carrier will ask all end user customers to have their affected TRUs
inspected by an authorized Carrier dealer. The dealer will, at no cost to end user customers, inspect and install the specified heat shrinks on the exposed wires, with an adhesive property to reduce the likelihood of the heat shrink falling off, within the affected TRU. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : Carrier Transicold is modifying the affected TRUs in the field by cutting off the stripped portion of the wire, and adding the heat shrink that contains an adhesive property to reduce the likelihood of the heat shrink falling off within the affected TRU.
All affected TRUs shipped on and after September 28, 2022, will have all of the wire ends cut off to remove the stripped and exposed ends, and replaced with new heat shrink with adhesive properties; and removal of 20AMP fuse F7 to ensure the wires are no longer live. Recall Schedule :
Description of Recall Schedule : On or before December 20, 2022, Carrier plans to send notice of the
updated inspection and field retrofit plan for affected TRUs via email to all authorized dealers located in the U.S., and plans to send notice of the updated inspection and field retrofit plan for affected TRUs via U.S. Mail to all known end user customers located in the U.S.

Supra S Series (S6, S7, S8, S9, S10) Part No. : 22-61124 Size : N/A Function : Refrigeration
Descriptive Information : The Supra S6, S7, S8, S9 and S10 models of diesel truck refrigeration unit (together, the “affected TRU”) are sold by Carrier Corporation’s Carrier Transicold Division (“Carrier”) and are designed and used to maintain the temperature of frozen and/or chilled products during on-road truck transport. The affected TRUs come with a 12V wire harness to provide power for a fuel heater post-production add-on accessory.
Production Dates : JAN 01, 2016 – SEP 22, 2022
Description of Defect :
Description of the Defect : The 12-V wire harness of the affected TRUs contain live power and have been found to be exposed when not attached to the postproduction fuel heater accessory, with stripped wire ends and a missing protection heat shrink.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : The exposed, live wires in the 12V wire harness in the affected TRUs could
potentially ground or have intermittent connection with surrounding cut wires or other metal components, which could lead to electrical arcing and localized heat. Hot copper from the wire could ignite a flame which could propagate to components in the surrounding area and result in an increased risk of fire. Description of the Cause : In the affected TRUs the wire harness is missing the heat shrink that protects Part 573 Safety Recall Report 22E-090 Page 2 Identification of Any Warning
that can Occur : the stripped wire ends, either as a result of not being installed by the supplier or falling off after production.
Visual inspection should clearly show the missing heat shrink in the area of concern on the wire harness. Involved Components : Component Name : 12-volt engine harness
Component Description : 12-volt engine harness (supplied by ECI) that provides power for a fuel heater add-on accessory
Component Part Number : 22-61124-01 (S6), 22-61124-00 (S7, S8), 22-61125-00 (S9), 22-61125-21 (S10) Supplier Identification : Component Manufacturer

Country : United States Chronology :
On August 16, 2022, Carrier received notification of a thermal incident involving a Supra S6 TRU in Aurora, CO. On September 14, 2022, a field inspection was conducted, with an independent third-party fire investigator, into potential causes of the thermal event. On September 20, 2022, a production line inspection showed that the affected TRU’s wire harness was missing the heat shrinks, such that the exposed wires in the harness may come into contact with surrounding metal or other exposed wires. As a result, all shipments of affected TRUs were put on hold on September 22, 2022, and Carrier immediately began a careful analysis of the affected TRU’s wire harness to assess the potential product safety risk. To date there has been only the one thermal event related to this issue, and no other field reports of arcing. After much internal analysis and discussion with safety engineers, on October 20, 2022, Carrier determined that the issue presented a potential safety-related defect reportable to NHTSA under Part 573. That same business day, on October 20, 2022, Carrier filed this 573 Defect and Non-Compliance Report. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 22E-090

Description of Remedy :
Description of Remedy Program : Carrier will ask all end user customers to have their affected TRUs
inspected by an authorized Carrier dealer. The dealer will, at no cost to end user customers, inspect and install the specified heat shrinks on the exposed wires, with an adhesive property to reduce the likelihood of the heat shrink falling off, within the affected TRU. Owners who seek reimbursement for the cost of a repair or remedy for this issue prior to Carrier’s notification are encouraged to contact their respective Dealer to submit the claim; if needed, more information about the procedure for pre-notification reimbursement claims may be found in the Manufacturer Pre-Notification Reimbursement Plan associated with this recall. The Plan also includes an address to which claims may be mailed. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : Carrier Transicold is modifying the affected TRUs in the field by cutting off the stripped portion of the wire, and adding the heat shrink that contains an adhesive property to reduce the likelihood of the heat shrink falling off within the affected TRU.
All affected TRUs shipped on and after September 28, 2022, will have all of the wire ends cut off to remove the stripped and exposed ends, and replaced with new heat shrink with adhesive properties; and removal of 20AMP fuse F7 to ensure the wires are no longer live. Recall Schedule :
Description of Recall Schedule : On or before December 19, 2022, Carrier plans to send notice of the
updated inspection and field retrofit plan for affected TRUs via email to all authorized dealers located in the U.S., and plans to send notice of the updated inspection and field retrofit plan for affected TRUs via U.S. Mail to all known end user customers located in the U.S.
