Make sure your RS232 is screwed in and not loose. Verify your PC is not hanging up and locking up the com port (windows can really suck some times).

I would scan-disk and defrag. I bet its not a furnace problem, but a PC problem.

We have link fail issue now & could not able to establish. Overall situstion is that oven can not work. we checked all relay 24vac, 24vdc, 110v, 120v, 240v. all looks ok. only issue we ovserve that from B250SSR pin no 3&4 we are unable to get 5VDC. These is connection in / out from FCU And also form SSR pin no 2 no out put come. Swapped SSR with other location , status is same. Any info, pl. check. ajay

Sounds similar to a recent problem with our VIP70. We thought it may be the SSR, then the FCU ... Swapping blower unit with a second oven finally helped us traced the problem to the thermoswitch inside the blower assembly.

Link Fail is the RS232 connection to the FCU.

I would check the connector, cable that plugs into the computer.

Verify all power supplies are working.

The most likely scenario is this:

Computer malfunction Cable / connector issue. Defecive FCU
