Recall 11V099 affects 1,320 2006-2010 Diamond Coach buses with loose evaporator fuses that can arc. Repair is free at franchised Diamond Coach dealers.

Diamond Coach is recalling 1,320 2006-2010 Ibd, Ps, Vip, and Pt buses equipped with Carrier GEN V EM-1 evaporator units because the fuse can loosen in its holder, creating high resistance and arcing. If enough arcing occurs, the fuse holder can melt with flame, smoke, and fire risk; the Diamond Coach dealer repair will be free once available.

What's wrong?

The Carrier GenV EM-1 evaporator unit is part of the bus air conditioning system on affected Diamond Coach Ibd, Ps, Vip, and Pt buses. The evaporator helps cool air before it moves through the passenger compartment, and its electrical circuit uses a fuse seated in a fuse holder to protect the unit from excess current.

On these 2006-2010 buses, time, temperature, and vibration can loosen the fuse inside the holder. A loose fuse does not make solid electrical contact. That raises resistance at the connection and can cause arcing, which is electrical sparking across a gap instead of current flowing cleanly through the fuse.

An owner or operator is not given a specific warning sign before this failure in the recall filing. There is no warning sign before failure, so the issue is found by confirming whether the bus has the affected Carrier GenV EM-1 evaporator equipment and completing the recall repair.

Who's affected?

Spans four Diamond Coach models across five model years, all with the air conditioner component.

2006 Diamond Coach Ps Air conditioner
2008 Diamond Coach Vip Air conditioner
2008 Diamond Coach Ibd Air conditioner

Units affected1,320

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.

What's the safety risk?

Electrical arcing can melt the fuse holder and lead to flame, smoke, and fire. Schedule the recall work promptly, and stop using the vehicle if flame, smoke, or heat damage appears. Repair will be free at any franchised Diamond Coach dealer once available.

What should I do?

  1. Check your VIN to confirm your 2006-2010 Diamond Coach Ibd, Ps, Vip, or Pt bus is included in this recall.
  2. Contact Diamond Coach or the Carrier hotline to get the free Carrier GenV EM-1 evaporator retrofit kit instructions.
  3. Schedule the retrofit kit repair that secures the loose air-conditioner fuse holder and addresses arcing at the fuse holder.
  4. Bring the recall notice if Diamond Coach sent one. If not, reference recall number 11V099 when you call.
  5. Watch for smoke, flame, or a burning smell near the air-conditioning evaporator area, and stop using the bus until it is inspected if those signs appear.

What happens at the repair

At the dealer, a Diamond Coach technician uses Carrier's retrofit kit and repair instructions to correct the fuse holder condition in the GenV EM-1 evaporator unit. The work addresses a loose fuse that can create high resistance and arcing. Because the campaign filing does not list the final remedy status, do not assume a same day appointment until the service desk confirms kit availability. The dealer repair is free once available.

What should I do if my 2006-2010 Diamond Coach Ibd, Ps, Vip, or Pt is on this recall?
