Arrived on site per customer complaint of no heat coming from furnace. Gave unit a call for heat and inspected furnace startup sequence. Inducer kicked on and HSI glowed until it ignited the flame. Flame stayed steady but the blower did not start and there was no hot air blowing from the floor registers of the home. Eventually the unit shut off, suspected to have tripped the high limit switch. Presented pricing for furnace diagnostic with and without membership pricing. Customer agreed to diagnostic with membership pricing. Disconnected power to the unit and took a reading of the capacitor, which gave a reading of zero microfarads. Diagnostics confirmed the capacitor is failed. Often times this is do to a motor beginning to fail but until this part is replaced we cannot determine the internal motor performance. Presented pricing for replacement of capacitor as well as replacement options for furnace. Customer decided to move forward with replacement of capacitor. Removed old cap
