Hi and welcome to the forum,

I am going to move your post to the 'All other HVAC Questions' forum. You will find it at this link.

Robert and maybe some others there would be better qualified to help you with this problem. They may need the Make, Model and other information.

Hi,

If the troubleshooting guide is followed and does not help any, time to call an hvac tech out to look at it.


The guide steps should lead to problem area.



Thanks,
Robert
