14-year-old water furnace premiere locked out on high pressure and water flow LED. Comfort alert compressor monitor active on short cycle alarm #2 Pressurized ground loops at 22 PSI, static off refrigerant pressure 178 Initial testing found no power to flow center caused by blown 10 amp L2 relay supply voltage fuse. Flow center has one of two pumps locked up. Due to the age and condition of the flow center individual pumps cannot be replaced. Confirmed alcohol-based antifreeze at 0.975 Repressurize ground loops to 60 psi Replaced blown high voltage 10 amp fuse for temporary operation with three amp fuse for flow center Disabled left side flow center pump Run test equipment in cooling mode. Current refrigerant pressures with 50% water flow potential are at 107 & 247. Refrigerant pressures will need retested and probably adjusted after full water flow and pressure are reestablished. The compressor discharge line service port currently has a very minor refrigerant oil leak nearly
