4 flashes on the XE80 means there is a problem with a high limit switch, usually due to excessive heat buildup. This could be caused by something restricting airflow, such as a faulty blower or a dirty filter. In a situation like this, it is always advisable to contact a licensed HVAC contractor to come out and take a look.
