Have HVAC Questions? Ask an HVAC Expert for Answers
Hello, one minute while I get some information together.
Have you changed the batteries in the thermostat and if so does the FAN come on when you set the thermostat to FAN ON?
Ok if the fan did not come on there is a good chance just the batteries are the issue. If the fan does not come on and ac that means the thermostat is not sending the signal. It can be on and look like it is working, but with low batteries it will not work. Have them change those and if it still gives you an issue get back to me.
All I ask is please select the ***5 STAR RATING*** using the link at the top of your page before leaving, that is the only way I am credited through the site, tips are appreciated.
