Apartment 306. Tech found a leak at the same spot that was repaired in April. Tech spoke with the office and was told to take care of the repair under service warranty. Tech brazed up the leaking section and pressure tested to 400 psi. Pulled down a vacuum below 500 microns and charged the system with 10lbs of R410a refrigerant system is back cooling.maintenance man was not on site prior to departure.

Upon arrival customer stated he believes system might of caused a power outage. Stated store lost power at one point and then came back on, tech inspected entire system. Both compressor amp draws are within spec, cycled system twice and came on and ran without any issues. Inspected proper voltage. Informed customer can’t duplicate issue if it’s even coming from unit. System was running upon arrival and departure.

Replaced thermostat wire

Upon arrival tech was informed system was not running. Inspected system and ensured setup was correct on Symbio. Tech checked for 24v on board and had 24v at R, Y1, G, Y2 and W1. Also heard inducer draft attempting to cycle on. Tech shut power off and disconnected wires at thermostat and inside system to check for continuity. Got a reading across R and W but no other wires. Disconnect the W wire from thermostat and used Brown on W1 and connected a jumper from W1 to W2 inside system. Turned power on system came back on. Tech recommends replacing thermostat wire to be able to connect W1 and W2 stages correctly. Will need 2 people to replace wire and approximately 60’ of wire. System is back operational at this time.

Techs re-diagnosed thermostat wires and found no shorts. Reconnected wires and shortened excessive thermostat wire inside the unit. System is operating normally at this time.

FOUND SYSTEM RECEIVING CONSTANT VOLTAGE FOR HEAT, EVEN WITH THERMOSTAT DISCONNECTED. ALSO ONLY SENDING PARTIAL VOLTAGE FOR COOLING INTERMITTENTLY, AND SOMETIMES UNABLE TO DROP CALL FOR COOLING CAUSING TO RUN CONTINUOUSLY. SEPARATED ALL THERMOSTAT WIRING AT THERMOSTAT AND UNIT. FOUND CONTINUITY BETWEEN R TO Y, BROWN(W1/2), AND Y2 (O). ALSO BETWEEN COMMON AND G. MULTIPLE SHORTS WITHIN THERMOSTAT WIRING. NO EXTRA WIRING TO WORK WITH. WILL NEED (2) TECHNICIANS TO RUN NEW WIRING FROM THERMOSTAT TO SYSTEM. FOR TIME BEING, TECH WAS ABLE TO RE-LOCATE THERMOSTAT TO INSIDE RETURN OF SYSTEM, AND TIE INTO SPLICE AT SYSTEM. EXPLAINED SITUATION TO MANAGEMENT. SET TO 72 PER REQUEST. SYSTEM IS NOW CYCLING PROPERLY. NEED TO CONTACT ASAP TO SCHEDULE REPAIRS. WARRANTY. SPOKE WITH MRS. HUTCHINSON.
