Automatic pilot light wont light on a honeywell furnace

You may be able to get a schematic from Honeywell that shows the connection points.

Unless you are using a current sensing relay or sail switch, you need to get the humidifier power from the blower motor supply so it only operates when the blower is on.

Since you can manually control the humidifier, there is not a fault with the solonoid.

Normal operation should require both the fan to be running and for the furnace to be heating before the humidifier will run. Check out the manual here: https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-2413EF.pdf

Clean pilot , replace thermo couple if it looks burnt out clean flame sensor

Honeywell tech support is awesome here in Minneapolis, I think you need seperate humidistats but check with HW, number is in owners manual.

Sounds like dirty flame sensor. You can either clean it orreplace it.

sounds like to me you have a condensation pump attached to your hvac system. this can be used to pump water produced during the cooling of your house when in the a/c mode. if you have a typical bypass humidifier, you will have excess water running past the water panel and it must be sent to a drain of some kind. I would imagine the pump is being used to get your bypass water to the drain. another scenario may be that you have a 90% condensing furnace. if your exhaust pipe for the furnace is made out of pcv pipe, it is a condensing gas furnace. it will produce water when it is running. the water if from the combustion gases being condensed in the secondary heat exchanger. this is normal. some condensing gas furnaces will draw combustion air from inside the house and some will have a second pvc pipe that is used to pulll combustion air from the outside of the house. either way, it is not dehumidifying your house. the humidifier should be able to keep up if it is runnng properly. you should have water running out the bottom drain of the humidifier any time the fan on your furnace is running and the humidistat is calling for humidity. if this is not happening, it is not wired properly.

check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

sounds like you need a gas valve or inlet pressure adjustment. You will need a proper pressure guage for this.

the first blower you hear is the inducer motor it pushes the exhaust out. sounds like abad gas valve.do you have a standing piloit light or is it eletronic ignition. if electronic and there is no glow you have a bad ignitor
