What should I do if the air conditioner indoor unit leaks? 10 days of solutions to popular problems
Recently, air conditioner indoor unit leakage has become one of the hot topics in home appliance repair on the Internet. As high temperatures continue in summer, air conditioners are used more frequently and water leakage problems occur frequently. This article will combine the hot discussions across the entire network in the past 10 days to provide structured solutions to help users quickly troubleshoot and repair faults.
1. Common causes and proportions of air conditioner leakage
| Reason | Proportion | Main performance |
|---|---|---|
| clogged drain pipe | 45% | Water overflows from the bottom of the internal unit |
| Installation tilt | 25% | Condensate cannot flow into the drain pipe |
| Condenser is dirty | 15% | Low cooling efficiency and excessive condensation |
| Sealant aging | 10% | Leakage in the drain pan or pipe joint |
| Insufficient refrigerant | 5% | Evaporator melts and drips water after freezing |
2. Step-by-step solution
Step 1: Check the drain pipe
• Turn off the power of the air conditioner and clean the drain pipe with a thin wire or special unblocking tool.
• Test drainage: pour a small amount of water and observe whether it is smooth.
Step 2: Adjust leveling
• Use a level to check whether the indoor unit is tilted (standard: the drain outlet side is 1-2cm lower).
• Re-fix the hanging board or raise the corresponding position.
Step 3: Clean the condenser
• After removing the filter, use a soft brush to remove dust from the evaporator surface.
• Spray air conditioner cleaner, let it sit for 10 minutes and then turn on the drain.
Step 4: Check for tightness
• Focus on checking the connection between the water pan and the drain pipe.
• Replace aging sealing strips or repair with waterproof tape.
