JA: Did you double-check the thermostat's settings? And what about the filters?

Give me a few more details.Tell me if you get a clicking or anything at outdoor unit o call for ac and if you have a volt meter for troubleshooting?

Customer: replied 8 months ago.
Looks like the capacitor is bad. It's original and about 16 years old. Top is domed and no readings on the ohm meter.

Look forward to hearing back as soon a you get capacitor

Customer: replied 8 months ago.
Put the new capacitor on and everything is working fine. Interesting that my blower motor, blower motor capacitor and air conditioner capacitor all went bad within 10 days. All were original equipment going almost 30 year on the blower and capacitor and 16 years on the air conditioner capacitor. But all functioning fine now.

Excellent news. That is strange but not that uncommon to have two issues at once.Customer often wonders sometimes when I go on a call and find two things totally unrelated wrong at same time, but it does happen.
