Upon arrival we found the indoor head unit would run for about 5 mins and then shut off and throw a constant code. The code was stating the outdoor condensing unit wasn’t sending signal back to the indoor head unit after 5 minute causing shutdown. After inspecting the outdoor unit inverter board burned up. Let customer know the issue and gave him options. The board is 5-6 weeks out, the customer wants a bid for a new system if the board cannot be delivered and installed soon. .
