2014-2022 Braun Ambulances Recall 22V911: HVAC Fire

Recall 22V911 covers 1,321 2014-2022 Braun Ambulances vehicles with HVAC relay overheating that raises fire risk. Repair is free at any franchised Braun Ambulances dealer.

What's wrong?

The front mount 110/12V AC condenser on these 2014-2022 Braun Ambulances vehicles is part of the heating, ventilation, and air conditioning system. The condenser fan pulls air across the condenser so the system can shed heat and keep the ambulance module climate control working. A relay acts like an electrical switch that turns the fan circuit on and off.

On the recalled vehicles, air movement while the ambulance is moving can spin an unpowered condenser fan. That spinning fan generates voltage back into the relay. Without a diode, which is a one-way electrical check valve, that voltage feeds back into the relay, overheats it, and damages the fan circuit. Once the relay fails, the condenser fan stops working and the HVAC system stops working.

The warning sign is direct: the front mount condenser no longer works. The 110/12V AC system will not function, so the ambulance loses that air conditioning function until the relay is replaced and the diode is added.

Who's affected?

Spans the Patriot, Express, Chief Xl, Signature Series, Super Chief, Tlc, Liberty, and Express Plus across the 2014-2022 model years, all tied to the front mount 110/12V AC condenser.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.

What's the safety risk?

A front HVAC system that overheats can fail and increase the risk of a fire. If the front mount condenser stops working or the AC system no longer functions, stop using the HVAC system and contact the dealer for the recall repair. Repair is free at any franchised Braun Ambulances dealer.

What should I do?

1. Check your VIN to confirm your 2014-2022 Braun Ambulances Chief Xl, Express, Express Plus, Liberty, Patriot, Signature Series, Super Chief, or Tlc is included in this recall.
2. Contact a franchised Braun Ambulances dealer to schedule the free relay replacement and diode installation that protects the HVAC system from condenser fan relay damage and overheating.
3. Bring the recall notice if Braun Ambulances mailed one. If not, reference recall number 22V911 when you call.
4. Stop using the HVAC system and contact the dealer if it overheats or fails before the repair.
5. Call Braun Ambulances customer service at 1-877-344-9990 with questions about scheduling or owner notices.

What happens at the repair

At the dealer, a Braun Ambulances technician replaces the condenser fan relay and installs a diode to protect the HVAC circuit from excessive voltage. Parts and labor are free under recall 22V911. The source repair time is 15 minutes, so the visit is built around a short relay and diode repair rather than a full HVAC replacement. Ask the service desk to confirm the recall number before work begins.
