20 Most Recent Slant Fin GF-210W 2 Gallon Humidifier Questions & Answers

First check to see if the two water sensing probes have been cleaned. After cleaning, if the problem still persists, try the following.

There is a small thermostat switch that sits on the heating coil underneath. This thermostat is designed to prevent the coil from overheating when no water is present. What probably has happened is the switch is doing what is designed to do but has become defective and is opening and closing at a lower temperature. So what is happening is the red light reset indicator will come on because this switch opens, the coil starts to cool and the switch closes and the light goes off. Because it is defective, this is occurring when it shouldn’t, causing this maddening on/off cycle.

Fortunately, this sensor is easy to replace if you’re handy. Make sure you unplug the humidifier from power. Turn it over, remove six screws, and carefully lift the lid. Look toward the heating element and you will see a small button type device with two wires plugged into it and is attached with two screws off to the side of the element. This particular thermostat is obsolete and very difficult to find. However, there is an excellent substitute made by Stancor for around $5.00. Their part number is STO-325.

Remove the two screws and lift off the thermostat and slide the wire connectors off. Simply reverse the process for installation and be careful to replace the bottom lid, being careful not to crimp the wiring.

I just bought a wet pack for my 78 series from a local supplier.
It is a Westwood No S70-45, wet sheet chamber liner. You cut it to fit then fire up the boiler and it sets up. The sheet measures 16'x48'. You can also get it online. Good luck

With this model it has not only been discontinued and difficult to find repair and replacement parts. I would suggest a new product. I wish that even in theses times I had more encourageing news because most of the time if its broke fix it..but this time, It's time to go shopping, also the company has sold twice, and now goes under two sub names. Have a great day. Thank you for your time.

The pad is very easy to replace. Simply remove the water tank. The mineral pad floats in the hot water reservoir. Pull out the old one and discard if it has begun to break down. That's all their is to it.

I hope this helps.

Most likely it is the water sensing transistor (C1815) in the unit. This can be replaced but it would have to be by someone who knows how to repair electronic instruments. The cross for the C1815 transistor is NTE85 and sells for about $1.50.

In the bottom of the humidifier is a little disk that vibrates to turn water to vapor. This gets covered in mineral deposits and won't vibrate properly. They usually suggest something like vinegar to clean it. I found that this didn't work for me. What did work was cleaning it with my Waterpic on the highest setting. It chipped away the deposits and allowed it to work. HOWEVER, once you get it running again, buy the slant fin mineral absorption pads to keep it running. If you have mineral-rich water like me, you'll go through them quickly, but you also won't have white deposits on your walls anymore.

Hello,

The refill/reset light comes on after the water level drops, Did you add water?

If so you might need to clean it twice.

Mine was doing the same thing...first month of operation (installed toward end of heating season) = no problems with noise (bubbling, gurgling) though the duct work - started second year toward middle of season. Now its been running for a few weeks and is intolerable. I dug out owners manual and it did not address this at all. I dug out the installation manual and viola! Gurgling is caused by excess condensation in the steam hose. Sure enough the steam hose had a small area depression and did NOT have the constant downward slope necessary - installation instructions are VERY specific about needing a slope in order to allow condense to drain from the steam house. The zip-tie installation had slide down from a vertical stabilizing pipe & allowed for the hose to sag in the middle (nice install job slacker). I adjusted it and the SOUND IS GONE. Hope this helps someone else.

Without brand and model, my advice is definitely a shot in the dark. Only your manual or your manufacturer's site can inform you of what the flashing means. Here are some tips that might help you increase the humidity in your room: Check the humidifier's water level: Make sure that the humidifier has enough water to function properly. If the water level is low, the humidifier may not be able to produce enough moisture to increase the humidity in the room. Clean the humidifier: Over time, mineral deposits and bacteria can build up in the humidifier, which can affect its performance. Clean the humidifier regularly according to the manufacturer's instructions. Place the humidifier in the right location: Place the humidifier in a central location in the room, away from walls and other obstructions. This will help the humidifier distribute moisture evenly throughout the room. Use a humidistat: A humidistat is a device that measures the humidity in the room and automatically adjusts the humidifier's output to maintain a desired humidity level. If your humidifier does not have a built-in humidistat, you can purchase a separate one and use it to control the humidity level in the room.

Is this a mist generator with an ultrasonic element, popular for "health?" These have a wick and water is not going trough the dry wick by itself. One should make all of the wick wet, from bottom to top. After that the water keeps being taken up to the element until the device is stored and the wick dries out again. Another thought is that these ultrasonic elements are very similar to a buzzer, like in toys. Two round sheets of metal with plastic in between. This is not like having long lifetime. For expensive mist makers you could perhaps order a new element but I do not have high hopes. Being so vulnerable the humidifiers are shipped containing no water. It is important to rest the top of the wick in water also. Just making the wick wet close to the element does not help or gives bad results.
