*Incomplete! Service disconnect is turned off* Southwest rooftop package system servicing the pharmacy corner of the building has experienced a high voltage electrical burnout/surge/unexplainable event that has blown out both 240 vac 30 amp service disconnect barrel fuses, the 5 amp 24vac fuse on the ignition control board, the ignition control board blower relay, and the blower motor itself has open windings.. After replacing the high voltage fuses the 240 power supply is stable including the high to low voltage transformer. The low voltage side is shorted to the high voltage internally in the ignition control board through the burned out blower relay. After attempting to permanently hotwire the blower motor with no success the windings have tested burned out in a open circuit condition Service disconnect fuses are in place (2 x HACR30) Blower motor with new capacitor needs installed Ignition control board needs installed Additional electrical testing may be required after the
Goosenecked the exhaust away from the intake. Windows in the vicinity do not open. Intake 45⁰ elbow is fine.
Status LED display on the control board flashes all of the information for current mode: heat percentage and airflow CFM, etc. No faults in the system. He's also complaining of the sound the furnace makes when it initially fires off the burners. Explained last trip (and reiterated today) that it is the expansion of the air inside the burner compartment the moment of gas ignition. This will be the last of the no cost trips.
Diagnosed with no heat in lobby 1 of 5 RTU systems Trane 2008 Found blower wheel stuck against the plastic housing Blower wheel is seized on the shaft. pulled the full blower assembly to adjust the depth of the motor bracket. Blower wheel is slightly out of balance but running good now System was running and at 68 set to 70 at arrival time today but would not start and was at 63 a couple days ago Remove flame sensor and spark electrodes for cleaning Inspect heat exchanger Inspect air filters. Inspect thermostat and batteries and test run multiple times for heat mode Unfortunately today I could not witness the broke down system. Several items needed attention but the no heat condition could not be positively identified System is running good set to 70 Air filters are very dirty Recommend regular maintenance on all RTU equipment
Furnace is in off mode upon arrival. Set thermostat to E-Heat to test furnace operation. Inducer motor comes on as it should, but ignitor does not come on. Found ignitor to have a failure in the glow line keeping it from getting hot. Replaced failed ignitor and test run in gas heating mode. No other issues observed at this time.
Performed maintenance on Daikin Fit dual fuel system Corrected an issue with the inducer clamp that was leaking water Pulled and cleaned flame sensor Went through thermostat settings. No relevant fault codes Run tested furnace and heat pump 17 degree temp rise with heat pump 48 degree temp rise on high heat for the gas furnace Filter is new All sounds/noises from the equipment are normal.

Upon arrival inspected units they were stressing concerns on and quickly discovered fully clogged filters for each head. Units looked like the build up was at least a year old. Wash filters and wipe down heavy buildup. Test ran all three heads for that room and all three were pumping heat out no problem after filters were cleaned.
Replaced outdoor coil. System working normally at this time.
Two system geothermal split equipment with gas furnace backups. Second floor equipment has third floor installed 80% gas furnace janitrol estimated 25 plus years old, basement system has replacement carrier high efficiency gas furnace estimated 2020 range 100K BTU , 2006 water furnace e series EZ040S10ANBSSA Both split geothermal systems are short cycling and intermittently locking out on water flow and pressure switches due to a faulty water furnace premier control board on the right side system. The relay and few circuit controlling the single dual pump flow center has melted and blown the fuse and is non-resettable All other functions of the control board appear to be normal Transfer high voltage supply to the flow center from the right side geothermal equipment to the left side geothermal system and Make the appropriate adjustment to the Twinning kit installed Repressurize ground loops from less than 10psi to 45 PSI for entering into heating season Install two 16X25x1 pleated

The primary cause of the water leak on the floor is a clogged 3/4-in drain trap from the evaporator coil leading to the floor drain. Inspect and flush evaporator coil drain pan and all drain lines and traps to the floor. Drain and flush gas furnace condensate trap. Resurface flame sensor and run test equipment in heating and cooling modes Install 2-in PVC vent drain kit, clean equipment in the burner compartment and treat the rust with an oil bath **Upper furnace door was left off intentionally so equipment can be inspected for water 1 to 2 times weekly during heating season Combustion blower assembly has condensate corrosion buildup around the bottom seams of the assembly and the heat exchanger collector box also has rust staining visible on the front. Equipment is currently safe to run but if water is found located anywhere in the upper or lower compartments during heating season those components will need replaced
