TROUBLESHOOTING YOUR HUMIDIFIER
Table 4. Troubleshooting Humidifier.
Problem What to look for What to do
Water
leakage
Leaking joints. Shut off water and tighten connections.
Brass tubing inserts Verify that brass tubing inserts are used.
Saddle valve leaking. If a saddle valve is used as the shut off valve, verify rubber pad is installed
on saddle valve.
No water to
drain.
Electrical Verify control circuit wiring.
Check all connections.
Humidistat Turn the humidistat up all the way. If “Humidity Boost” appears on the
screen the H6062 is calling for humidity. If it does not, the installer might
not have enabled boost and it is possible very cold outdoor temperatures
could be restricting humidity.
Humidifier power Verify that outlet has power.
Solenoid After verifying other wiring components, turn on furnace fan, turn
humidistat up and down, and listen for solenoid to click.
Plumbing Verify plumbing connections.
Check for kinks. Verify shut off valve is in open position.
Shut off valve Verify shut off valve is turned on. If a saddle valve is used, verify that needle
pierces water line and then backs out needle to open valve.
Humidifier Remove cover and verify that water flows into distribution tray.
Drain tubing Verify no obstructions.
Air leakage Check duct joints Seal with foil tape.
Low
humidity
Furnace blower not
operating.
• Reset circuit breaker or check for blown fuse.
• Check that the furnace power is on.
• Check all external wiring connections.
• Check the humidity control setting.
• Verify that pressure switch tubing isn't pinched or obstructed.
• Call a professional heating contractor.
Rapid air changes.
Drafts (cold air is dry
and is an added load
to the humidifier).
• Keep doors and windows closed.
• Close fireplace damper when not in use.
• Keep exhaust fan running time to a minimum.
• Seal around doors and windows.
Damper in “summer”
position.
• Set damper blade to "winter" position to allow humidification.
High
humidity
Condensation on
walls.
• Turn off humidity control and water until condensation is completely
evaporated.
Heavy condensation
on windows.
• The H6062 can be set for frost control if outdoor sensor is used. If
already set for window protection. If frost protection is enabled, and you
still get condensation, lower the setting on the H6062.
