How do I reset my AC pressure switch?
Locate the high pressure switch near the compressor (a cylindrical device piped into the refrigeration system with two wires a red button on the top). Push in the button to reset. Push the rocker switch to restart the unit. The thermostat will be flashing temperature with the !
How do you know if a pressure switch is bad?
Here are some tell-tale signs that your pressure switch is beginning to fail: Your water pressure is at or above the cut-out pressure, yet the pump doesn’t turn off. Your pump doesn’t turn on at the proper cut-in pressure. You have low water pressure even though the pump is running.
What would cause an AC clutch to not engage?
What’s Preventing the A/C Compressor from Engaging? One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power.
What happens if AC pressure switch goes bad?
As the pressure switches control the on/off function of the AC compressor, a switch failure can prevent the AC compressor from functioning at all. The compressor is what pumps refrigerant through the entire system. If it is not functioning, then the system can not operate, and will be unable to produce cold air.
Can you bypass the AC pressure switch?

What is the function of the AC pressure switch?
The AC pressure switch function is to provide a safety monitor over the system. It is responsible for monitoring refrigerant levels on both the low- and high-pressure sides of the AC unit.
How do I check the pressure on my air conditioner?
Check AC Pressures. Use your air conditioning gauge set to check for adequate levels on both sides. You will attach the low-pressure gauge to the low-pressure fitting and vice versa. On the low-pressure side, you should see readings near 30 PSI when the temperature outside is 90 degrees or less.
