Possible Causes of a Dripping Aprilaire Humidifier
When an Aprilaire humidifier leaks or drips water, here are some of the common culprits:
- Clogged water panel – Sediment, dirt and minerals can obstruct water absorption in the humidifier panel, causing water to overflow the tray.
- Drain line blockage – Debris in the drain line prevents water from draining properly, leading to leaks and backups.
- Internal leak – Cracks in evaporator pads or seals around internal tubing can lead to inside leaks.
- Float valve failure – A stuck float or one not rising properly can lead to overflows from the water reservoir.
- Excessive mineral deposits – Hard water minerals can severely limit the panel’s water absorption and cause water to pool.
- Improper installation – If the humidifier is not level or the drain line positioned incorrectly, leaks can result.
- Excess humidity level – An extreme humidity setting beyond the size of the humidifier’s output leads to condensation buildup and drips.
Thoroughly inspecting your Aprilaire unit and identifying the drip location can help diagnose the problem source. Next we’ll cover specific steps to fix it.
How to Troubleshoot and Repair an Aprilaire Humidifier Drip
Follow this complete troubleshooting guide if you notice water coming from your Aprilaire humidifier:
- Turn off power and water supply – This ensures safe access and prevents flooding.
- Check for panel obstructions – Remove the panel and look for any debris, dirt or mineral blocking absorption.
- Clean the panel – Soak the panel in distilled vinegar, then scrub with a brush and rinse clean. Minerals and sediment blocking water absorption will dissolve.
- Inspect the panel – Examine closely for any cracks and order a manufacturer replacement if cracked.
- Test drain line flow – Disconnect drain line and ensure no clogs by running water through.
- Check float valve – Remove any dirt buildup from the float valve. Confirm it moves freely to control water flow.
- Examine internal gaskets – Tighten any loose gasket fittings or replace cracked gaskets allowing leaks.
- Verify humidity setting – An extremely high setting can lead to excess moisture and condensation drips. Lower to 45-50% range.
- Confirm proper angle – Check humidifier is level for appropriate drainage. Adjust angle if needed.
- Replace drain tubing – If drain flow seems restricted, replace tubing with a larger 1/2 or 3/4 inch diameter size.
With common trouble spots addressed, the dripping should resolve in most cases after you reinstall parts and test unit operation.
Preventing Future Aprilaire Drips
To help prevent drips long-term:
- Change filters per manufacturer instructions
- Keep humidity settings under 50% maximum
- Clean the panel every 6 months with vinegar
- Flush drain lines annually
- Replace worn gaskets and seals
Proper Aprilaire maintenance goes a long way in avoiding leaks!
When it Pays to Call an HVAC Professional for Drip Repairs
While many Aprilaire drip issues can be DIY repaired, in certain cases it pays to call in an experienced HVAC technician. Recommended scenarios include:
- Persistent dripping even after troubleshooting steps
- Leaks originating from internal gaskets or components
- Concerns over significant water damage from unresolved drips
- Drain line requires extensive snaking or hydrojetting
- Mineral deposits severely clog internal waterways
- Electrical issues prevent the float valve from working
- The unit requires recalibration of the angle or stability
- You are uncomfortable accessing electrical or water lines
- New installation drips make you question positioning
HVAC pros have specialized tools, testing equipment and expertise to fully diagnose and fix complicated Aprilaire dripping issues. Their comprehensive repairs can provide peace of mind and prevent future problems.
Stop Annoying Aprilaire Drips in Their Tracks
While it can be worrying to see your Aprilaire humidifier leaking, identifying the source of the drip and taking focused troubleshooting steps can solve many problems through DIY repairs. But for major internal leaks or extensive mineral buildup, don’t hesitate to bring in an HVAC professional.
Stopping annoying Aprilaire drips quickly prevents damage and dangerous electrical and slip hazards. With some periodic maintenance to minimize dirt, debris and mineral accumulation, your Aprilaire should provide years of drip-free operation for whole-home humidification. Breathe easy by keeping your humidifier operating at its best.
