Please check the bellow article to verify for any bad installation in page 4.


The major reason for the humidifier furnace not working is due to a bad humidistat, fan switch or float switch--problems that take specialized equipment to diagnose. But before you call in a pro, it's worth your time to test the fan motor and float assembly, since repairing them is something you can handle on your own. Let us know if you were looking of something else.

With the remote kit all you need is a small hole to get into the supply duct. That should be possible in most any situation.

The problem you will have if you install it into the return is that the steam could cause corrsion inside the furnace, and or cause problems with the blower motor, from the extra moisture.

If I would chose to install in the return duct I would want at least 6-10 ft. of duct and an elbow before the furnace to assure that the air fully absorbs the steam before it gets to the furnace. I would then monitor the blower compartment to check for moisture building up in there.

If you do not have it here is the manual that shows the prefered installation and how the remote works.

Adjust your humidistat to lower humidity level. If you do not have a humidistat, get one and install following mfg guidelines. Home Depot sells one for about $30

the most practical solution is install a new evaporative pad every year. But if you would like to squeeze "a little" extra life out of the pad . Try soaking it in a solution of 1 part white vinegar to 2 parts water.
