So after the compressor turns off the fan runs an additional 45 seconds, then turns off for 2 minutes, and the fan turns back on for 45 seconds & cycles like that until the compressor comes back on? How often does the compressor cycle back on?

I installed a Houghton 2801 AC on my Parkliner trailer. The compressor also cycles on/off about every 4 minutes. I don't understand why. I'm wondering if one of the temperature sensors isn't calibrated or working properly and the AC thinks the indoor temp has been reached or coil temp is too low. I modified my AC to install a relay on the low speed fan to try and reduce the humidity, but with the short cycling it's not making much difference.
