Carrier Gas Furnace, burner shuts off stating error code 33 and/or 13

[FrankMTL]

I have a Carrier Gas unit 9300TS model 58MTA100. It is combined with a multizone system as well as a Heat Pump. The system works great on the heatpump but as soon as it goes on EM HEAT and runs on the gas furnace, it works for about 10-15 minutes than the burner shuts off and the board gives me error 33 and/or 13. Which seems to mean limit switch error... I tried by passing the limit switch and it seems to work ok. I am thinking of replacing the limit switch HH12ZB190 (190 Degree)? Any suggestions, will this fix the problem?

is the high limit adjustable? if so try lowering the high set point a tad and trying it. if you have a multimeter, check the switch on the lowest resistance range for continuity - if it reads open replace it.
