Technician was knowledgeable and courteous.
Performed routine maintenance per energy savings agreement. Technician did not find any challenges at todays visit. The system is heating properly and holding a delta t of 20+ degrees. One recommendation the tech had is to replace the contactor in the system. The one currently in the system is showing signs of pitting. This is a sign of potential future failure. Tech recommends replacing to avoid system downtime and a future service call. Estimate built and added to system for customer review
Tech found 5 amp fuse blown inside dining room AHU 2. Tech replaced fuse and it did not blow again. Heat strips, blower, reversing valve, compressor contactor, and defrost cycle each energized correctly without blowing fuse. Tech cycled system multiple times in each mode without any issues. Turned tstat call off and found 0 volts between blue common and all other tstat wires in the off cycle. Tech checked continuity on tstat wires and found black tstat wire (24 volt hot wire to outdoor unit) in outdoor unit tstat bundle has continuity with the ground screw in the kilo ohm scale. Tech swapped black wire currently being used for red for green wire. Green wire has no continuity with ground screw. Tested system in each mode again. Defrost board is getting 24 volts and system ran in each mode again without blowing fuse. If fuse keeps blowing, we will need 2 techs to replace 45 feet of tstat wire between AHU and outdoor unit. Install warranty.
