A compressor that repeatedly blows fuses is drawing too much current or has a short circuit. This guide finds the cause safely.
Electrical Causes
- Undersized fuse or supply cable.
- Low or unbalanced voltage.
- A failing motor winding or contactor.
Mechanical Causes
- Starting against full tank pressure.
- A stiff or failing air end.
- High ambient temperature raising current.
Fixes
- Check fuse and cable ratings.
- Test voltage and motor current.
- Reduce starting load or repair the air end.
What fuse size does a compressor need?
Match the fuse to the motor nameplate current and starting method, with the correct curve for motor starting.
