Furnace wasn’t heating and I couldn’t read the codes. Cycled furnace. O igniter but the gas came on. 120v to the igniter and igniter is open. Talked to customer about the issue and repair vs replacement. They was tied to get heat on and are planning to replace the furnace early next year. Gave the customer on option of prefoming a cleaning. Replaced th igniter and tested the heat exchanger and preformed a combustion test to insure safety. Everything operating properly. Thanks Brad
