Carrier furnace- Resolving high limit error code 33

Resolving high limit error code 33 (or lockout error code 13) can be challenging, especially if the problem is intermittent. Verify that airflow is good, gas pressure is good, and furnace temp rise is within range, if they all check out normal, the likely culprit is the high limit switch. But wait! Don’t replace the switch just yet! Try securing the insulation surrounding the high limit switch tighter to the cell panel inlet and you will be amazed with the results! The furnace will run and run without prematurely tripping the high limit switch. You will ask the question, “why didn’t I think of that?” This solution is very easy, inexpensive, and can be accomplished with equipment you already have on hand. #hvac #carrier #gasfurnace
