Can a blown fuse make my AC not work?
If the fuse is blown, the air conditioner will quit working and you’ll need to have your AC repaired. Repairing a blown fuse is an easy and inexpensive repair job.
What happens when your AC fuse blows?
If your air conditioner blows a fuse, it stops working, so you definitely know something is wrong. You might hear a humming noise coming from the unit, but your AC won’t blow cold air. The fuses in your AC work like the circuit breaker in your electrical panel.
Where is the a / C relay on a Kenworth W900?
The A/C electrical system on a W-900 is pretty simple. One 30-amp fuse runs the blower & supplies power to the A/C clutch. It’s located on the bottom row of the fuse box, on the right-hand side. The A/C relay is located above that. There is also a 5-amp fuse for the HVAC control box mounted in the dash.
What to do if the clutch is bad on a Kenworth W900?
If you have power at the compressor, and the clutch isn’t engaging, the clutch is bad. If you don’t have power at the compressor, go to the high-pressure switch. This switch is normally closed. If you have power here, use a “paperclip” to jump across the plug itself. This will complete the circuit & activate the compressor clutch.
Where is the freeze control on a Kenworth W900?
It’s located on the bottom row of the fuse box, on the right-hand side. The A/C relay is located above that. There is also a 5-amp fuse for the HVAC control box mounted in the dash.
