Was performing a PM on a new client with two Trane split systems. 410A
Model# 4TTA3060A30000BB 208 3ph
Serial # 110751R15F
When I was checking the condensers, I notice the fan motors would lose power for a brief second. I noticed they both had the factory low ambient kits on them. Part # BAYLOAM103. It was about 70 degrees out so I would think that they should not be cycling at all. There was no literature with the unit so I could not diagnose the problem. When I disconnected the OAT sensor on each unit they both stopped doing it and ran fine. The green led on the board seemed to flash odd also without a steady heartbeat when the fans would lose power. I did not have time to check the charge but that was my first thought that they may be low on refrigerant. I also noticed a red LED flashing but again I had nothing to tell me what it was. If anyone can get me the info or has experience with this type of low ambient that would be great. Thanks in advance.
