Lennox CB28UH-030 Ignition Control Board
The main reason to have an ignition control board is that it may control the gas valve, the ignition sequence and some more sensing equipment. It has always been a vital electronic circuit board that, in most cases, has become a major component of the main board instead of its own individual board.
Clues of a poorly working ignition board
- HVAC ignition system refuses to begin even when called upon
- Initial communication from the remote thermostat never turns up at the main control board
- Every other potential issue within the furnace is looked at and turns out to be OK

If you decide on picking up or purchasing do your best and cross-check the model number and also make a visual inspection in order to be sure the right ignition control board is the one being purchased. HVAC pros may charge higher prices than others so you may want to keep a lookout locally to acquire the best rate if money is of great importance to you.
