Hi AB, I am mr.grzz,
thanks for your questions, well first off there is no fixing the pressure switch, it will have to be replaced, you will need your model and serial number on the furnace, make of furnace, to order a new one from a parts supplier, fairly easy to replace.first make sure the power is off to the furnace, undo the two wire leads on it, then the two screws holding it in place, remove the one or two small hoses attached to it, if you remove it before you go to look for a part, that would be best, there is a rating on it, just follow these steps in reverse to put in place, hope that helped ya, thanks again, mr.grzz

How much water gal/hr is reasonable to expect from the furnace humidifier overflow in "0 degree" farenheit outside to heat a 1500 square foot normal midwestern house to 72 degrees inside having a norm


There is no flow rating because it would depend on too many factors. What you do need to check is the float valve. The water valve is opening and closing like it should be but the reservoir is filling too much.

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.

2005 Aprilaire 700 humidifier. Replaced a non-working circuit board. Now, the humidifier works fine when the furnace is running. It starts and stops as it should based on humidistat setting. Problem: ...


It sounds like it is just miswired. The low voltage wiring off the humidistat should be on W and C on the circ. board at the furnace. If you have it on R and C then it will power it constantly regardless if the heat is running or not. W is only energized on a call for heat which is typically when you want that type of humidifier to run

Coleman kersene furnace in mbile home, (furnace is only 4 years old--just inspected 3 months ago) However,it ran fine last night, now it will not come on unless you hit the ret switch, then it tuns 20-30...


Sounds like a fuel or ignition problem. If the unit does ignite when its reset it could be a bad Cad eye or primary control. If it does not light off when reset,DO NOT re-rest anymore and call the Heating contractor back to inspect and repair.

Aprilaire 500 - Everything works, but humidity will not increase!


You should take out that aprilaire and throw it in the garbage or return it to who you got it from. Ask them why they didn't offer you the best humidifiers available. The only way to truly control humidity in your home without running your heat is a steam humidifier. Autoflo makes a good one also honeywell makes a new one. I have installed a honeywell tru steam in my own home and a few customers it hasn't lived up to its advertising. The auto flo has never given me any problems with customers.

Furnace keeps running, no heat


The pressure switch is not allowing the igniter to heat up. Pressure switch is blocked or the flue is blocked. Take the draft fan off and inspect the flue. Also inspect the rubber hose connecting the fan and pressure switch make sure the ends are tight. Make sure the hose is clear and not restricted. And the pressure switch sometimes is position sensitive. I don't think it has been moved or anything. And very rarely do they go bad.
