Gentherm Blanketrol Warming Units Recalled for Overheating Risk: Health Canada

Health Canada has classified a Type II recall for Gentherm Medical’s Blanketrol® II 115V and Blanketrol® III 115V patient temperature management units after the manufacturer reported overheating circuit boards in a small share of distributed devices. The recall, identified under reference number RA-82413, was issued on July 13, 2026, and published by Health Canada on July 28, 2026.

The Blanketrol II and III systems are hospital-grade hyper/hypothermia units used to warm or cool patients through connected blankets or pads. According to Gentherm Medical, the company has received complaints of overheated circuit boards affecting approximately 0.53 percent of the devices it has distributed.

Products Affected by This Recall

The recall covers Blanketrol® II 115V units with model number 222S and Blanketrol® III 115V units with model number 233. Several specific serial numbers tied to the 222S model have been identified, including 151-2-01474, 151-2-01472, 114-2-00258, 131-2-00535, 124-2-00447, 124-2-00490 and 114-2-00259. For the Blanketrol III model 233, Health Canada notes that more than ten serial numbers are involved, and facilities are asked to contact the manufacturer directly to confirm whether their specific unit is affected.

What Went Wrong?

Gentherm Medical determined that a portion of circuit boards inside the affected units are prone to overheating. When this happens, the circuit board can stop operating altogether. In practical terms, that means a device could fail to power on at startup, or it could shut down unexpectedly while actively delivering therapy to a patient.

Despite the malfunction risk, Health Canada notes that the probability of harm is considered low, and no injuries have been reported in connection with the issue. Because of this, the agency and Gentherm Medical are not asking hospitals and clinics to immediately pull the units from service. Instead, facilities are being told they may continue using the devices while taking a simple precaution.

Who Is Affected?

This recall is directed at healthcare and industry users rather than individual consumers, since Blanketrol units are hospital and clinical equipment rather than home medical devices. The notice falls under Health Canada’s general hospital and personal use, and cardiovascular, device categories, reflecting the equipment’s use in surgical, critical care and recovery settings where patient body temperature must be closely controlled.

What Consumers Need to Do Now

Because reported harm has been absent and the probability of malfunction is low, Health Canada is not recommending that facilities stop using Blanketrol II or III units outright. Instead, the agency recommends the following steps.

• Continue using the device as normal unless it shows signs of malfunction.
• Keep an alternative means of providing patient warming or cooling therapy on hand, in case a unit shuts down unexpectedly.
• Check serial numbers against the affected list, particularly for Blanketrol II 115V model 222S units.
• Contact Gentherm Medical directly for guidance on Blanketrol III 115V model 233 units, since the full list of affected serial numbers was not published.
• Report any device malfunction or safety concern to Health Canada through its online reporting tool.

From the Agency

Health Canada’s published notice states that Gentherm Medical ‘has received complaints of overheated circuit boards in 0.53% of distributed devices,’ and that this overheating ‘can cause the circuit board to stop operating, which may result in a device that shuts down at startup or during use on a patient.’ The agency adds that, ‘based on the low probability of harm, and absence of reported harm, associated with this issue, users may continue to use the device,’ while recommending that ‘in an abundance of caution’ an alternative therapy option be kept available.
