Replace indoor air coil, filter dryer, 144 oz new R410A, oil dye with leak stop, 80uf compressor capacitor, repressurize ground loops ***The job is incomplete The system compressor is not running yet*** After replacement of the blown out air coil and recharging of 144 oz of new R410A the true cause of the original problem is without a doubt a thermostatic expansion valve failure in the 100% closed position causing the head pressure side to reach maximum pressure and blow out the weak points in the coil. Suction pressure is dropping below 60 and cycling on low pressure The air coil replacement is complete however the system now needs a replacement thermostatic expansion valve. And repressurized ground loops after the system is running The system is on, fan mode and emergency heat mode should work normal The CXM is locking out on service code 5 low pressure and freeze protection Seth will prepare repair estimate ASAP
