Lennox elite air condition unit outdoor not turning on

Did you tried to plug in the cable in another room, where you are sure that electricity works? How long it is since it last worked? Do you have it under warranty?

My lennox furnace works just fine except that 25% of the time the fan keeps running when it shouldn't and blows cold air

You are using too restrictive of an air filter. If the codes you are getting off the lights says anything about a high limit this is the cause of your blower running all the time. Use a less restrictive filter or have your contractor install a media filter in the system. if you reset the furnace and it does not stop running the blower you have a stuck limit switch and may have to get another or call a service tech to reset it or replace.

No water flow through solenoid

The water flow through the humidifier is limited/controlled by an orifice. This small opening can easily clog. After disassembly use a small wire to clear the debris trapped in the small hole,

Hope this helps?

I hear no water draining from my heathy soluions lennox humidifier just put in a new filter

None leaking? Try removing the cover, and manually cycling on the controler switch? Does the solenoid click on, next to the humidifier (the unit with the water line running through it, with wires coming out of it)? If it does click on, is water running down the water pad? It doesn't necessarily drain water when it's working correctly. All of the water SHOULD be getting evaporated into the air return duct.

If it's clicking on, but no water is running out, you should check the water supply saddle valve and make sure it wasn't turned off during servicing.

If it's not clicking on, you should test that you are getting voltage (12v-18v DC) to the solenoid. If you're not, check all wiring connections and make sure they're tight. If you still don't get power, you have either a problem with your control unit/humidistat, your DC power supply, or the control board on your furnace.

Have a aprilair 550 for some time. Installed a new Lennox G61MP furnace and the technitions failed to reconnect the wiring that powers the humidifier. Need wiring schematic. Does humidifier transformer get...

Hello, yes the transformer will get a 120 volts from the Furnaces control board, there should be a terminal labeled HUM on the control board. You need to bring 2 wires one from HUM and one from a nuetral tap on the board to the line side of the transformer, this way every time the blower motor on the Furnace turns on the humidifier will aswell.

Lennox humidifier not working

It could be a number of things.. the most common is the unit is not getting any water the saddle valve not open or the solnoide valve not getting any power to the valve. the Humidistat not turned up high enough should be around 35 to 40%. The damper not open. The screen to the orfice limed up.

How do I check whether my Lennox humidifier (made by Aprilaire) is getting current going to the valve solenoid? I've checked across the wires going into the valve and found no current. Thanks for your...

If you are not getting voltage to the solenoid valve then start at the transformer and check if you are getting 24 volts. If not then turn off power to the transformer and set your meter to continuity and check the transformer, if you dont have continuity the transformer is bad and must be replaced. If the transformer is good then check the wring to make sure the connections are tight and the humidistat, if that check out good then the current sensing relay/ sail switch is bad.
