Coleman-Mach 48000 AC short-cycle breaker trip
The Coleman-Mach 48000 AC owner manual says the compressor needs two to three minutes for pressure to equalize after shutoff; restarting too quickly can short-cycle the compressor and trip a breaker or overload.
Owner-safe checklist
- Turn the selector or thermostat off from normal controls and wait at least three minutes before retrying a cooling call.
- Avoid repeated off-on cycling when the compressor does not restart immediately.
- Record whether the fan ran, whether the compressor tried to start, and whether a coach breaker or overload tripped.
- Use a qualified technician or electrician if trips repeat after the normal waiting period.
