Came out for a no heat call. Customer stated that the system wasn’t heating properly. We were out recently for the same issue and couldn’t find anything wrong. I checked system over and found the control board is faulting out intermittently and cutting the system off and putting it in lockout after a couple faults. I discussed repair vs replace with customer. Gave customer estimates for a new system. Customer wanted to just do repair for now. Installed a new universal control board for customer and cycled furnace to check operation. System is now heating properly.
