Question about Honeywell Power Humidifier: Furnace Humidifier/ Humidifier

Wall heater does not work!

I have a tri-plex in CA built in 1949. The 1 bedroom units have small heaters built into the wall. They are not very efficient, if they work at all.
I can not get one of the units to even light? I've replaced the gas valve and a thermocouple. I even blew out the gas nozzles and the burner area. Still I can't get the burners to light. The pilot light works but that's all. The place I bought the valve from says that's all I should need. I'm not sure of the model numbers If they're there, they have 30 coats of paint over them.
Any suggestions?

It sounds like the gas valve is not getting power. There is probably a saftey device that has tripped, preventing the voltage (24v) from energizing the gas valve. check for 24v throughout the circuit. It should be a simple series circuit.

Hi, We just purchased a vicks warm mist humidifier. We used it for two nights in my daughter's bedroom...we then noticed a sticky residue over sections of the wall as well as crackling paint? Is this...

is it possible that you have the mist turned up too high? If the room is very small, the high setting could be providing too much humidity to the room. I'm thinking that the paint crackled as the humidity climbed.

How do I remove the thermostat cover to change the battery?

Many of the newer Honeywell models have a battery compartment that can be accessed without removing the thermostat.
Look for a small tab at one of the top corners of the thermostat. If this is not the case try pulling directly away from the wall at the bottom, then tilt up.

There is no water flowing, i just replaced the solinoid, could it be the humistat? 700 sieries aprilaire

Could be, test it...if you have an OHM meter, set it to resistance and disconnect the humidstat. With the humidistat set all way on, you should get 0 ohms, if not it is bad. You most likely have a wire not connected somewhere, You need to have 24 volts at the solenoid when the heater is on and the humidistat > than existing humidity %. That is the bottom line. So check first at the electrical plug that the transformer is plugged into, if it does not use a wall transformer, test the furnace circuit board to see that you are getting 24Volts from the HUMIDIFIER TERMINALS when the HEAT IS ON. Then check the humidistat like I stated above. Solenoid is good cuz you replaced it.

Brivas (ME35)Heating/Cooling unit, error?

Hi there, I know that this unit is made in South Africa and it is well built and designed. The problem sounds like a condensation problem, and instead of the water draining at the condensate line hose, or pipe, it is over flowing into the electrical components causing the unit to trip loosing power .I have not been able to locate a manual to read what the codes for this unit mean, but you need to look at the unit where the water is coming from, the evap. coil where it blows supply air and clean the drain and if it has a foam type filter that can be washed, do this also.The drain must be washed or blew out or you will continue to have this problem, which can also be dangerous as you no that water and electrical products do not mix. If it will not come back on now after the water has drained, it sounds like the water has finally damaged a component. Find out what you can on this code from owners manual if you have one. Sometimes you will find a list of codes on the unit also, that will tell you what so many short or long flashes mean. I would bet the water has shorted out a component.Lets hope not, try and find what this code means and we can go from there.It would be great to be on site to get you up and running, such Luck. It only condesates in the cooling mode inside the house. Please inform me what you find.
Sincerely, Shastalaker7

Won't humidify past 30% in a 90sf bedroom

The most probable reason that the humidifier does not reach the levels you describe is because you said you had the unit in your bedroom.

Bedrooms typically contain materials that are known as "hygroscopic." What that means in plain English is that items such as the bedding, mattress, any carpeting, wood, curtains, you, etc. all absorb moisture , kinda like a sponge. Since that moisture is being held by these materials, the air itself contains less by percentage. 25-30% humidity is actually pretty good for any room, especially in colder climates and higher humidity levels can lead to the production of mold, condensation on windows, etc., which are not good things. The good news is that reasonable humidity levels are healthier for textiles such as carpeting, cloth, and so on because the fibers won't dry out and crack. Dust is also reduced, but again, only to a certain level.

If your humidifier is reaching 30% it's probably working ok.

My 7142 leaks

There are a few hose connections inside the unit related to the heater element. Water flows from the reservoir down into the unit, takes a turn into a tube with the heater element wrapped around it, then turns back up into the mister area. Any of the four connections (base to first elbow, elbow to heater tube, heater tube to second elbow or second elbow to base) could be leaking.
The white ring around the mister disk cracked on my unit, letting water leak out the bottom as you describe... Take a close look at that.
It's also possible the base itself is cracked somewhere... Look closely at the mister and reservoir areas of the base for cracks.

Thermostat - Honeywell Chronotherm III

What you can do is try and clean the contacts. Open the door on the thermistat and remove the two screws, after that you can seperate the part that is mounted to the wall and the front panel. Look at the part that is mounted on the wall and you'll see the contacts that should be a copper color. They might be black from age. Clean them and you'll be surprised how well it will work after that.
