Whether you're in downtown Toronto, Mississauga, Brampton, or anywhere across the GTA, a leaking refrigerator is one of the most common appliance problems we get called out to fix at TrueFix Appliance Repair.
The good news? In many cases, the cause is simple — and you can often diagnose it yourself in under 15 minutes. The not-so-good news? If left unchecked, a leaking fridge can damage your flooring, warp cabinetry, and even lead to mould growth in the humid Toronto summer months.
In this guide, we'll walk you through the five most common reasons your refrigerator is leaking water, how to check for each one safely, and when it's time to call a professional.
- Unplug the refrigerator or switch off the breaker before pulling it out from the wall
- Have towels ready to absorb water
- Never use sharp objects on plastic tubing or drain lines
- If you smell anything burning or see scorch marks, stop and call a technician immediately
1. Clogged Defrost Drain (The #1 Culprit)
What it is: Your fridge has a small drain at the back of the freezer compartment that funnels condensation away during the defrost cycle. Over time, food particles, ice, and debris can clog this drain.
- Water pooling inside the bottom of the fridge or freezer
- Ice buildup at the bottom of the freezer
- Water leaking onto the floor from the front or under the fridge
How to check it
- Empty your freezer and locate the drain hole (usually at the back floor of the freezer compartment)
- Look for ice or debris blocking the opening
- Pour a small amount of warm (not hot) water into the drain using a turkey baster
- If water doesn't flow through, the drain is clogged
DIY fix: A mixture of warm water and a drop of dish soap, flushed through the drain with a turkey baster, often clears minor clogs. For stubborn ice blockages, you may need to defrost the freezer for 24 hours.
When to call TrueFix: If the clog is deep in the drain line or you've cleared the visible blockage but water still pools, the issue may be further down the line and requires disassembly.
2. Frozen or Damaged Water Supply Line
What it is: If you have an ice maker or water dispenser, your fridge is connected to a water supply line. This line can freeze (especially in older Toronto homes with cold basements or kitchens against exterior walls) or develop cracks over time.
- Water leaking from behind or underneath the fridge
- Reduced water pressure from the dispenser
- Ice maker producing small or hollow cubes
- Visible water trail leading from behind the appliance
How to check it
- Pull the fridge away from the wall (carefully — Toronto kitchens often have tight clearances)
- Inspect the plastic or copper water line running from the wall to the back of the fridge
- Look for cracks, kinks, or visible ice on the line
- Check the shut-off valve for moisture or corrosion
DIY fix: If the line is kinked, gently straighten it. If it's frozen, unplug the fridge and let it thaw for a few hours.
When to call TrueFix: Cracked supply lines, faulty inlet valves, or persistent freezing issues require professional repair. Improper repairs can lead to flooding — and Toronto water damage claims aren't cheap.
3. Cracked or Misaligned Drain Pan
What it is: Underneath your fridge sits a shallow plastic pan that catches condensation. Heat from the compressor evaporates this water naturally — but if the pan is cracked, dislodged, or overflowing, water ends up on your floor.
- Water leaking only from underneath the fridge (not inside)
- The leak is slow but consistent
- You can hear a dripping sound from below
How to check it
- Unplug the fridge
- Remove the kick plate at the bottom front (usually clips off)
- Slide the drain pan out and inspect for cracks or excessive water
DIY fix: If the pan is simply dislodged, reseat it properly. If it's cracked, you'll need a replacement — and most Toronto-area parts suppliers stock common models.
When to call TrueFix: If the pan is consistently overflowing, it usually points to a deeper issue (often a clogged defrost drain — see #1) that needs professional diagnosis.
4. Clogged Evaporator Coils or Excessive Frost Buildup
What it is: Your evaporator coils handle the cooling process. When dust, pet hair, or frost builds up, the system can't drain condensation properly, causing water to drip into places it shouldn't.
- Fridge isn't cooling as well as it used to
- Frost buildup visible inside the freezer walls
- Compressor running constantly
- Water leaking inside the fridge compartment
How to check it
- Unplug the fridge
- Locate the evaporator coils (typically behind a panel inside the freezer)
- Look for excessive frost or visible debris
DIY fix: A full 24-hour defrost can clear minor frost issues. Vacuuming the condenser coils underneath or behind the fridge every 6 months also helps prevent this.
When to call TrueFix: If frost keeps returning, the defrost heater, thermostat, or timer may be faulty — these are not safe DIY repairs.
5. Faulty or Worn Door Seals (Gaskets)
What it is: The rubber gasket around your fridge door creates an airtight seal. When it cracks, hardens, or warps — common in older Toronto homes where temperature swings stress the rubber — warm humid air sneaks in, condenses, and creates excess moisture.
- Condensation around the door frame
- Door doesn't "suction" closed
- Increased energy bills
- Water pooling near the front of the fridge
How to check it
- Close the door on a piece of paper — if you can pull it out easily, the seal is weak
- Visually inspect the gasket for tears, cracks, or warping
- Clean the gasket with warm soapy water — sometimes built-up grime is the issue
DIY fix: Clean the gasket thoroughly. Warm it gently with a hairdryer (low setting) to reshape minor warping.
When to call TrueFix: Replacing a gasket properly requires the right part for your model and careful installation to avoid future leaks. We carry common gaskets for most major brands serviced across the GTA.
When to Call a Professional Refrigerator Repair Technician
While many fridge leaks have simple causes, you should call TrueFix Appliance Repair if:
- The leak persists after basic troubleshooting
- You suspect a sealed system issue (refrigerant leaks)
- Your fridge isn't cooling properly along with leaking
- You see electrical issues, scorch marks, or smell burning
- Your fridge is under warranty (DIY repairs may void it)
- You're not comfortable pulling the unit out or disconnecting water lines
A professional repair almost always costs less than replacing your fridge — and certainly less than repairing water-damaged hardwood floors.
Why Toronto Refrigerators Leak More in Certain Seasons
Toronto's climate creates unique challenges for refrigerators:
- Summer humidity (June–August): Higher humidity increases condensation, putting more strain on defrost systems and door seals
- Winter dryness (December–February): Cold basements and exterior-wall kitchens can freeze water supply lines
- Spring thaw: Older homes with foundation shifts can cause fridges to sit unevenly, affecting drain pan alignment
Regular maintenance — including coil cleaning, gasket inspection, and drain flushing — twice a year can prevent most of these issues.
