I have a 1993 gas furnace that will not light. I have 1 blink on control board. I installed a new igniter and flame sensor. So when I try to start the induction motor starts then a few seconds later I hear a click but the igniter doesn't click at all then I hear another click sound then it shuts off and gives me the blink code again. Also it does not have a pressure switch, I assume it is because it is an outside unit? Also bypassed roll out sensor and did not light, then bypassed the aux limit switch on fan blower and did not start again. I do smell propane when it cycles through the steps but the igniter is the step the always malfunctions. Thanks in advance for any help.
