SE North Dakota | Last summer put a new compressor accumulator and orfice tube in. Also had put that new low pressure switch in. Then noticed this week that it cycles a lot. When I bypass it the pressure will read 21-24 on low side and 150-180 with engine fan running at 1100 engine RPMs. Like it said the standby pressure is like 90 when it sits. Just wondering if this low pressure switch trips at too high of pressure. I tried another one and it does the same but it was also the cheaper one. | |
