I have a Carrier Weathermaker 58SX furnace... Lately when it starts up, the exhaust motor starts but the ignition does not always catch... It'll click a number of times then shut down and then the sequence will start again. This will go on until it ignites properly and the furnace starts up and runs until the desired temperature is achieved.
Do I have a dirty flame sensor or some such problem... Would appreciate any help you can provide
Thank you
Danny
