Completed heating tune up, thermostat was out causing 5amp fuse to pop instantly. Bypassed it so I could complete tune up. Capacitor for blower motor was also out of 10% range. Informed customer & he said to just replace the capacitor & he would take care of the thermostat. Also let him know he needed a 5amp fuse due to the one in circuit board being burnt. Other than that the heating is functioning properly. No other issues to report.
