Question about Honeywell Heating & Cooling

2 Answers

Hi I have a furnace mounted model HE220 A,B which I installed about 2 years ago. This year, it doesn't send water into the humidifier, I checked the saddle valve and tubing and when I disconnect the tube from the solenoid valve, water comes out of the inlet tube but does not come out of the tube leading the the humidifier pad. Please tell me if the solenoid can be taken apart and cleaned, or is it necessary to replace the valve entirely? Thanks, John Strandell phone 920 748-5310 PS the solenoid makes the usual click when I turn up the hemostat. The furnace blower is running

    Please credit my account for the $6.00. I was not talking about an air conditioner, but my Honeywell humidifier. Your response makes no sense whatsoever!

Hi,
Taking apart the solenoid valve is never a good thing... they rarely work well when reassembled...
It is best to change it out...but before doing that make sure that you have 24vac coming to the valve when it should be opening... maybe there is an electrical problem and you don't want to find that out after you have replaced the valve...

So... check for power to the humidistat and for power through the humidistat to the valve...

Do this Add vinegar to it and let stand overnight. It will remove the scale and should run properly again the next day

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.

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.

Honeywell HE260 housing melted/deformed


Humidifiers are made from a very durable heat resistant plastic. If it melted or warped you have a serious overheating problem. That plenum should not get over 140 to 155 degrees. If this furnace is running to hot it could stress and crack your heat exchanger. Install a good carbon monoxide detector in your home!!!! Check your filters. Check your airflow. Make sure all registers in the house are open. Is your blower speed set high enough? If this furnace is operating to hot it is definitely worth the investment to have a pro look at it before you replace the humidifier.
Is this overheating problem new? Or was this something thar happened years ago and may have since been solved But you are just now noticing the heat damege that was caused.
Goog luck

Honeywell furnace humidifier thermostat & other


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.

Aprilaire 600 Humidifier


J-

I had this problem several years ago. In order for the water to flow, the outside temperature sending unit must indicate to the controller that it is less than 60F. If not, the unit will not operate outside of test mode. Check the temp outside where your sending unit is (could the sun be heating that side of the house?) and ensure that the circuit to the sending unit is working. I had a bad wire splice inside a wire nut stopping the circuit. Took me a long while to figure it out.

If the outside temp and your sending unit circuit is ok, I wish you luck on your troubleshooting.

Install HE220 HoneyWell , humidity not increasing in the house.


You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.
