What? Your humidifier quit on you? Try these troubleshooting tips before you send it back to the manufacturer or into the trash!
1. Check your humidistat
A humidistat functions as an automatic detector – it monitors the humidity levels in a room or house and turns the humidifier on or off accordingly. If you sense something amiss with the device, you should check the humidistat. It should work well with your heating system, especially during winter.
- Check your electrical control panel for a tripped circuit breaker or blown fuse. Replace the blown fuse.
- If this is not the problem, set the humidistat at a higher level (higher than the current humidity in the room).
- Switch off the electrical service panel.
- Open the humidistat body for examination.
- Using a volt-ohm meter, attach a wire clip to the two terminal screws.
- Switch on power to the humidistat. If the drum operates, the humidistat is faulty and requires replacement.
- To replace the humidistat, switch off the power at the electrical service panel and disconnect the humidistat.
- You can purchase a new humidistat from your local electronic and home equipment store. Install the replacement unit.
2. Check the float control
The hollow float inside a humidifier helps control water level. You will need to refill the reservoir from time to time.
- Open the water reservoir panel.
- Fill the water to an appropriate level and determine whether the float rod is straight.
- Adjust the float switch is necessary.
- Tighten all connections to the float.
- If faulty, purchase a new float and replace the faulty float.
3. Check the fan motor
Usually preceded by unusual noise, a faulty fan motor may require servicing or replacement.
4. Check your evaporative pad
- Clean your humidistat. A dirty filter or damaged filter foam can be cause for the problem when the humidifier is not cleaned and maintained regularly.
- Purchase water conditioners to soften the water and reduce algae formation. This helps to make your unit last longer.
- A clean pad prevents emission of bad smell.
