Carrier Infinity thermal lockout low/high stage
Carrier Infinity central AC system installed in 2006. Has worked flawlessly until last night.
Yearly filter changes (MERV13); both sets of coils clear.
I'm getting constant thermal lockouts on both high and low stages. Power cycled unit via circuit breakers several times. This allows the unit to start after a 7 minute delay, and it will continue to run for about 10 minutes and cut back off.
Does anyone have any experience with these units and can possibly point me in the right direction?
