Capacitor in condenser unit failed and is no longer in range which caused compressor not to run. Compressor is running at 21.3 amps which is close to its max operating range.
Check blower motor and amperage check capacitor for blower motor checked all electrical connections check primary drain line checked amperage all condenser fan motor found amperage high pulling 0.08 and rated at 0.09 check compressor amperage check Freon levels found free on low added refrigerant check evaporator coil evaporator coil clean
Check blower motors amperage check blower motor capacitors file capacitor for downstairs unit weak replace capacitor check primary drains on both units check secondary drains on both units checked all electrical connections took temperature differentials on both units checked all ductwork check amperage on compressors and condenser fan motors check contactors on both units check capacitors on both units check Freon levels on both units all good at this time
Repair: capacitor on inducer draft motor was failed on arrival, causing the draft motor to overheat and cause damage to the draft motor. Recommend replacing draft motor assembly to return the inducer draft motor to working order. Replaced inducer draft motor assembly and heater is operating normally with a 31 degree temperature rise. Also replaced thermostat with new T6 wifi thermostat. System is operating normally at this time.
Capacitor common line was blown up from an electrical surge, capacitor partially melted from surge, pitting on contactor and unit was low on Freon. Performed wire repair, capacitor replacement, contactor replacement and charged unit with customer supplied freon.
Diagnostic showed what looks like bite marks on electrical, repaired wires with electrical tape and shorting stopped. If shorting continues due to power surges or bite marks it could cause catastrophic failure of new blower or other electrical components.
Call back: low voltage wires for blower came loose at unit. Would run blower for short period, then shut off blower while keeping heat on. Resecured the wires back together and verified tightness. System is heating normally at this time with a 24 degree temperature rise.
Repair: blower motor and capacitor had failed upon arrival. Blower was spinning very slowly. Capacitor was bulging and dead. Recommend replacing blower motor and capacitor to get unit operating normally. Blower and capacitor have been replaced and system is running heat and cool normally at this time.
AC repair: found voltage short on wires rubbing against copper. Contactor has pitting which will cause damage to compressors and motors. Torque booster has oil around the rim. Need to repair wires replace torque booster and replace contactor, recommend installing surge protector to prevent surges from destroying compressors and motors. Replaced for booster and contactor and wire segments. System is operating normally in cool at this time.
Maintenance: System is operating normally at this time, achieving a 19 degree temperature split at this time.
Maintenance : both units functioning properly with an 18 split average. Motors amps and capacitors are all in range. Drain lines did have a little clog for the downstairs unit that was blown out and cleaned. Filters were changed out for both units. Customer agreed to sign up for comfort club silver and a additional unit.
Ac repair: found unit with almost no refrigerant. Recommend recharging the system and performing a leak search. Charged the system with 9 lbs. R410A. System is cooling normally now, achieving an 18 degree split.
Both systems low on Freon, customer supplied R-22, coils are clean, blew out drain lines, added drain tabs to pan. No float Switch on either System. After refilling with Freon both systems have a 20 degree split and are performing well within manufacturer specifications.
Maintenance: Cooling temperature split: 20.2°F system is operating normally at this time.
