Schools and facilities using certain Airedale by Modine ClassMate or SchoolMate heat pumps may be affected by a recall covering about 6,061 units in the United States. The ventilation-fan motor can short circuit if water reaches its circuit board, creating an overheating and fire hazard. The verified next step is to contact Modine or a certified Modine technician, request written instructions for temporarily disabling the ventilation fan, and arrange a free inspection and repair or replacement. The notices do not list a claim deadline, refund option or affected U.S. states.
Which Modine products are included
The recall covers ventilation fans installed in two Airedale product families: ClassMate DX cooling and air-source heat pumps, and SchoolMate water- or ground-source heat pumps. These systems are used to provide heating, cooling and indoor-air ventilation in settings including classrooms, according to the recall information.
The supplied recall details identify these model and ventilation-configuration combinations:
- CMD with ventilation-configuration digit 9 listed as C, D or E
- CMP with digit 9 listed as C, D or E
- SMG with digit 9 listed as H, J, K, N or P
- SMW with digit 9 listed as H, J, K, N or P
- CMS with digit 9 listed as H, J, K, N or P
The Airedale brand name appears on a sticker on the front of the unit. The model name and serial number are on the serial plate underneath the control unit. Because the supplied notices do not provide serial-number ranges, checking the unit’s model and serial plate is necessary before assuming it is included or excluded.
Why the ventilation fan is a safety issue
The hazard is tied to the ventilation-fan motor and its electronics, not simply to the heat pump’s heating or cooling function. The CPSC says water can reach the circuit board and cause a short circuit. That can make the unit overheat and pose a fire risk. Modine describes the same issue as electrical arcing within the blower assembly that may occur when water contacts the electronics during operation, potentially leading to a thermal event.
This distinction matters for facility operators deciding what to do next. Continuing to run a ventilation fan while waiting for routine maintenance is not the same as arranging recall service. Modine says users whose units have not been serviced should temporarily disable the outdoor-air and exhaust-air ventilation fans, or switch the internal disconnect to the off position. The company says written instructions are available on request.
What owners should do now
- Check the equipment. Locate the Airedale sticker, model information and serial plate beneath the control unit. Compare the model and ventilation-configuration details with the recall list.
- Contact Modine. The company lists a toll-free number, 888-636-8627, available Monday through Friday from 8 a.m. to 5 p.m. Central time. It also lists the official administrator and its recall page as contact routes.
- Ask for written shutdown instructions. Do not guess at electrical-disconnect procedures. Modine says written instructions can explain how to temporarily disable the affected ventilation fans while service is arranged.
- Arrange the remedy. Contact the Modine distributor or a certified Modine technician for the free inspection. The stated remedy is to inspect and repair or replace the recalled ventilation fan.
Modine says inspections and remedies have been ongoing since March 2026. That does not create a published deadline, however, and the supplied notices do not say that filing a request guarantees a particular appointment date or additional payment. The stated benefit is free recall service rather than a cash refund.
What is known—and what is not
The CPSC recall is dated August 20, 2026, and identifies about 6,061 U.S. units. The notice also says about 735 units were sold in Canada. Those figures describe the recalled population reported by the agency; they do not show how many units remain in operation or how many have already been serviced.
Modine says it is not aware of reported injuries associated with the matter. That statement should not be read as evidence that the hazard is harmless. The identified failure can lead to overheating and fire, so the practical decision is based on the equipment’s model and service status, not on whether a facility has already seen a malfunction.
The available information leaves several consumer-action questions unanswered. It does not identify affected states, provide serial-number ranges, state a deadline for contacting the company, or announce reimbursement for previously completed repairs. It also does not establish whether every unit in the listed model families is affected without checking the configuration and serial information. Facility managers should obtain confirmation from Modine before treating a particular unit as recalled or cleared.
The next verifiable step
The most useful record for an owner is confirmation from Modine or the servicing distributor that the unit has been inspected and what repair or replacement was completed. Until that occurs, operators should follow Modine’s written instructions for disabling the affected ventilation fan and preserve the unit’s model and serial information for the service request. A later update from the CPSC or Modine could clarify serial ranges, deadlines, completed repairs or other remedies; none of those details is verified in the supplied notices.
This is a facility-safety recall rather than a conventional consumer refund program. The strongest evidence is consistent across the CPSC notice and Modine’s own recall page: certain Airedale ventilation fans can short circuit when water reaches the electronics, and the remedy is inspection followed by repair or replacement. The practical trade-off is temporary ventilation disruption while the equipment is made safe. Owners should verify the model and configuration, request written instructions before changing the electrical state of the unit, and document the completed service. The evidence does not establish a deadline, cash payment, affected states or serial-number ranges.
