My compressor is cycling on and off every few seconds. I bought one of those recharge cans with the pressure gauge attached, because I assumed it was low. When I hook up the line, the reading varies from about 25 to 45 (compressor engages at 25, shuts off at 45... this happens every few seconds). I don't want to add any refrigerant, since the pressure is where it should be. What should I check next?
