Need to reschedule with smaller technician to fit through closet scuttle. <br> <br> <br> Wadeh<br> 12/29/2022<br> <br> <br> Customer concerned about unit not heating properly. Checked thermostat calibration and filter location. Checked blower motor operation and inspected equipment cabinet. Found Easy acces with pull down latter. Located 5 amp fuse burnt out and failed. Replace fuse and checked unit operation. <br> <br> Fuse is still tripping, has low voltage short in low voltage wiring. Checked all wiring connections and located outside thermostat wiring is touching the ground and the wire is bad. Choose extra wiring and hook up low voltage wire orange. Test unit operation and unit is cooling well and running heating properly. <br> Highly recommend new germicidal uvc light to prevent biological growth in air handler coil. <br> Recommend new safety surge protector on outside condenser unit to prevent voltage spikes and electrical failure on control board. <br> <br> Suggest new Taps
