Arrived at call for no heat and found fuse to be popped. Installed new fuse so I could try to locate short but the system fired up properly at this time. Found Knick in wire on G by control board and fixed it up as there could have been vibration that caused the short. Thermostat also is off the wall due to construction and concern that there is an intermittent short within the wall. Customer discussed that the wiring is ran properly from putting up new sheet rock. System operating upon my departure. Thank you for choosing LBA services. Your technician today, Jake.
