Hamilton 12hf humidifier stopped working

I removed the humidistat from the duct and blew it out, same with the electronic controller. There is power detected at all connections, and all connections are tight. I can hear the humidistat clicking when humidity changes. Any help would be great.

SOURCE: Installation problem

I WOULD CHECK TO SEE IF YOU HAVE ENOUGH V/A OUT-PUT ON TRANSFORMER. I DONT KNOW IF YOURS CAME WITH ITS OWN TRANSFORMER. IF IT DIDNT YOU SHOULD HAVE A MINIMUM OF A 40 V/A RATING STAMPED OR PRINTED ON THE EXISTING TRANSFORMER. IF THE TRANSFORMER IS EXTREAMLY HOT ... YOU MAY NEED A 75 V/A TRANSFORMER WITH THE SAME VOLTAGES. INCREASING THE V/A CANNOT DAMMAGE ANYTHING IT JUST GIVES YOU MORE POWER WHEN EXCESIVE CONTROLS AND WIRING ARE ADDED TO A HVAC LOW-VOLAGE (24v) CIRCUIT. IF YOU LIKE YOU CAN CALL ME AT 727-363-7071. I AM A RETIRED HVAC&R CONTRACTOR WITH 45 YEARS EXPERIENCE. I HATE THE NEW SENSORS THEY HAVE TO ACTIVATE THESE NEW HUMIDIFIERS. I USE TO WIRE THE HUMIDIFIER TRANSFORMER (SUPPLIED WITH HUMIDIFIER) TO THE LINE (110V) SIDE TO THE LOW SPEED ON YOUR BLOWER MOTOR. THAT WAY THE ONLY THING THAT INTERUPTS THE CICUIT IS THE HUMIDISTAT. YOU NEVER WANT THE HUMIDIFIER TO RUN IF YOUR SYSTEM IS NOT "CALLING FOR HEAT". NEVER TRY TO ENERGIZE THE WATER SOLENOID THROUGH YOUR HEAT WIRE(USUALLY SMALL THE WHITE WIRE) FROM THE THERMOSTAT. THIS WILL RESULT IN BURNING YOUR HEAT ANTICIPATOR OUT ON THE T-STAT.

SOURCE: Looks like my humidistat calls for coil fan and for furnace heat

It sounds like the humidifier may be improperly wired.
It's hard to solve without checking the wiring, but it seems like the humidistat is wired so that as the dial is advanced, it incorrectly turns on the fan, or furnace, or both.  The contacts of the humidistat should be wired so that they turn on the solenoid only.  Also, the power to the humidistat, to turn on the solenoid, should come on only when the fan is on.
Hope this helps!

SOURCE: Wiring issue with the Honeywell HE360A Humidifier

Maybe I can help. this is 24v so it doestn't matter which wire goes where so here goes. 2 wires from humidistat go to furnace, split one of the wires(not both) so they reach the yellow wires on the humidifier. with marettsconnect one of the split wires to one of the yellow wires. do the same to the other split wire and yellow wire. what you should get is one wire from humidistat to furnace then one wire from humidifier to humidistat and one from humidifier to furnace. hope this helps

SOURCE: Honeywell HE260 leaks somewhere

Neither, even if the solenoid or humidistat stick, it should always drain properly. Is the unit mounted on the cold air return duct or the supply plenum? If it's mounted on the supply plenum, the water panel might be getting blown forward and spilling the water. High efficient furnaces also can leak water on the floor if its drain is restricted. If hum. is mounted on return duct make sure drain is clear by blowing through it. On Honeywell hum's I've seen the rubber hose from the solenoid valve to the distributor tray leak too, check the rubber 1/4" hose.

SOURCE: This regards an Apriaire 700 that was installed

Hi,

You are absolutely thinking correctly....the humidifier should be running when ever the blower is running and the humidistat is not satisfied...in fact in some cases I have advised people even turn the fan switch on to run the blower longer to get more humidity in the air if needed....some furnaces do not have long enough run times to get enough water evaporated...

You have the idea of how it needs to go, so you should just go ahead and wire it up that way and you'll be glad you did!! You can get a relay for a few bucks and have a much better working system...

Honeywell humidifier short cycles


It's not uncommon for duct work in an older home to Bang as the furnace cycles due to age. The humidifier banging while turning on and of is mostlikely the solenoid valve; if the solenoid is bad it is actually to your benefit to replace the entire humidifier as the solenoids are very expensive, 50%+ of a new humidifier. Plus you get the 5 year parts warranty on the new unit instead of just one year on the solenoid. If you don't want to replace the entire unit you can replace the Humidistat, and that should fix the on/off cycling, however a new humidistat is included with a new unit, which again is more cost effective. They are easy enough to replace as a do it yourselfer, especially when replacing an existing unit. I hope this helps you.

Hello, in order to turn your humidifier on with the furnace the 120 volts coming from your humidifer you must hook it up to a step down transformer, then the transformer will provide 24 volts to you humidistat and solenoid valve. So you need a wire from the HUM on your control board to transformer primary side and a wire from neutral on the board to primary side of transformer. Then you need low voltage wire from secondary side of transformer to humidistat from humidistat to humidifier.

Do you feel like looking at the humidifier yourself?
You can open the door on the unit, while the furnace is running--
The humidifier is usually installed in the return air duct, so there will be a sucking of air into the open door, when you open it.

There is usually a large wheel, with a wet pad wrapped around the circumference.
This wheel rotates slowly, and picks up water from the sump-- does everything look and sound quiet as it runs? -- The float valve has to open and close, to c ontrol the leve of water in the sump-- (The pool of water the wheel runs the mat thru--
Possibly the valve shutting off, could make a plumbing BANG-- you could duplicate that, by lifting the float mechanism and stopping the water-- does that make the noise?

If you can reach and operate the Humidistat control from near the humidifier, do so a few time-- or Have someone cycle the humidistat a few times, and you listen for that sound--
Is it in the humidifier itself, or the duct work nearby?

It might be that the humidistat wheel scrapes against the side of the sheet metal duct work? -- Sounds travel a long ways in metal duct work!

Let us know if this helps

Wired a new 360 through Hum blew 3amp fuse. How to wire so it doesn't blow fuse. Have open EAC and EAC2.


Review figures 5, 6 and 7 on the installation instructions and compare with how you wired your installation.
The red wires are not used if you use a mechanical humidistat, (are used with electronic humidstat - supplies 24 volts and go to "hot", "commod" on humidstat). Yellow wired to "Hum" whether electronic or mechanical humidistat used.
If using sail switch or current sensing relay, cuts into one of the yellow wires. - One yellow goes directly to humidisat, then comes out of other side of humidistat & runs to to relay (or sail switch), and comes out of relay (or sail switch) and runs back to humidifier.

It's a little unusual to add a humidifier in Florida. The ambient humidity is usually high enough.

But anyway, if you want to do this and assuming you have central air with forced air heating, you could install the humdifier in a standard configuration, then use a sail switch or differential pressure switch in the supply air duct to turn the humidifier off or on when you are in the heating mode only. The sail or differential switch will ensure that the unit can't run unless air is moving and you can tie the humidistat in to the first heat stage.

Our aprilaire humidifier is only 4 years old and it does not seem to be working. We have static in the house and when I did test mode it never drained water like it was supposed to. Any ideas what I can do...


Hope this helps, check and see if humidistat is set to 35% humidity and that bypass damper on humidifier is in the open position or winter position.(humidistat is usually located on cold air return duct near furnace). Next, replace humidifier media pad, remember to replace media pad (filter) annually, you also may want to clean any lime deposit out of humidifier housing with a solution of warm water and white vinegar before installing your new media filter.Remember to turn power off at side of furnace when cleaning humidifier and replacing media. Before installing new media turn power back on to furnace, set humidistat to the on position, turn furnace thermostat above room temp., and inspect humidifier to see if water is running from top,(you may want to have a bucket under humidifier when checking for water), if you see water running, turn power back off to furnace, properly install new media filter, reconnect humidifier cover & set humidistat to 35%. If you do not see water present, check water supply valve to humidifier and make sure its turned on. If water supply valve is open, then check water supply tubing for blockage.And the last things to check is to make sure all registers through out your home are open and not blocked by any objects, also make sure furnace filter is cleaned, if none of this works refer to installation manual to see if humidifier was sized and installed properly, Good luck.

Aprilaire 600 just installed and showing an error code


No, it is not an accurate statement.

These units have simple configurations They have a water supply similar to a ice making referigerator, an enclosure connected to your supply duct that houses a prop fan and media, a seperate humidistat and a drain for excess water. Your unit may also include fancy controls including an outside thermometer & humidistat to avoid over humidification that can cause problems during freezing weather. The humidistat looks a lot like a thermostat and is located in your living space or in the return duct. The prop fan in the box pulls air from the duct, through evaporation media and back to the duct. An electric solenoid valve releases water that pours over the media.

If the humidiy is below the humidistat seting and the AC/heater is running, the Aprilaire fan starts and the solenoid valve opens. I suspect the facier controls include the flashing warning light.

The warning light spells problem. Aprilaire's customer service should be able to provide guidance for the homeowner in the form of simple checks. I suspect your contractor is avoiding a warentee call and the trip it requires.

A word of caution. These humidifiers can be powered directly from your air conditioning unit control board from an auxiliary connection. If the control board isn't rated to carry the current required by the Aprilaire fan, valve and controls or the Aprilaire encounters and electrical problem, the board can be damaged. This can be avoided by using a relay. The AC board switches a low energy relay. 120 volt house power is connected to load side of the relay and runs the Aprilaire.

My board cooked at a location near this connection, but I can't be sure that the load from the humidifier caused it since four of our neighbors also lost their board. It failed the evening of a snow storm and required a costly emergency after hours service call. The next day a new board required a three hour drive. Fortunately a fan powered propane heater kept our pipes from freezing.

Doesn't run


When a humidifier doesn't run, it generally means it isn't receiving electrical power or the controls have automatically shut it off. 1) Be sure it's plugged in to an outlet that works and that it's turned on. Check the electrical receptacle for power, using a working lamp, appliance, or voltage tester. 2) If the receptacle seems to be dead, check the circuit breaker or fuse that serves the humidifier's circuit. 3) Check the setting on the humidistat. If it's set lower than the room's relative humidity, the humidifier won't go on; in fact, it may take several hours for the humdistat to respond to the room's changing humidity. 4) Be sure the humidifier's reservoir is full of water. 5) Unplug the humidifier unit. 6) Check the power cord. If necessary, repair the cord. 7) Remove the humidifier's cover panel. 8) Remove the humidistat and check it (as shown below). Replace it if necessary. 9) If it still doesn't work, call an appliance repairperson, take the unit into an appliance repair shop, or replace the unit. To check the humidistat, you?ll need a volt-ohm meter. A humidifier?s fan vaporizes the water in the reservoir and blows the water vapor into the house or room. If you need to check the fan, unplug the humidifier, remove the control panel, and lift the lid. Tighten the fan hub with pliers if it is loose; this should take care of rattles. If the fan doesn?t spin easily when you try to move the blades by hand or if it is still noisy, lubricate the motor bearings with oil. To establish whether power is reaching the humidistat when you know there are no problems with the plug or switches, unplug the humidifier, remove the control panel, and lift the lid. Test it with a volt-ohm meter set to the RX1 scale (or to K[omega symbol] or [omega symbol] resistance on a digital meter). Clip the meter to the humidistat terminals. The meter should jump if you turn the humidistat from high to low. If it doesn?t, you?ll need to replace the humidistat or return it to the manufacturer.
