for Hilliard, OH
I found the flame sensor needed to be cleaned. I cleaned it and system is now functioning properly. I also noticed the ignitor had a hot spot on it, showing it could fail at any moment. I informed the customer of this and quoted them a price to think over. System is operational at departure.
I completed the service maintenance agreement tune up on a Carrier gas furnace. I visually inspected the unit. I cleaned the flame sensor. Checked voltages, amps and pressures. I adjusted gas pressure down to 3.5 per manufacturer's specifications. Completed combustion analysis. Cycled and monitored system. Operating normally at this time.
