Furnace Maintenance: Checked operation of thermostat. Washed EAC filters and cell. Checked for gas and co leaks. Cleaned furnace housing, blower and burner compartments. Pulled and polished flame sensor. Cleared pressure ports and tubing. Hot surface igniter starting to fail with white spots and burnt off silicone???? Checked amp draws on blower motor and inducer motor. Found that the inducer is really noisy but within amp draw range. Checked capacitor R:10 A:9.1 mfd. static total .8" w.c. Which is really high and needs to be taken care of when replacing equipment. Combustion check 10.2% oxygen and 34 ppm which is low but due to restrictive duct work it’s actually ok. Temp rise was 48 degrees. Took temp split throughout home. Replaced failing 10 mfd capacitor and also replaced failing hot surface igniter. Recommended service club membership for the AC.
