How to clean a removable drip pan

The drip pan in your refrigerator collects defrosted ice and condensation from the freezer section. Over time, the standing water in the drip pan can allow germs and mould to grow, causing a stink. To prevent this, it is recommended to clean your drip pan every three months. The first step is to locate the drip pan, which is usually found at the bottom of the fridge, either at the front or rear.

Accessing the Drip Pan

If your drip pan is located at the rear of the fridge, you will need to pull the fridge away from the wall and disconnect the water and power supply. You may need to unscrew a back panel to access the drip pan. If your drip pan is located at the front of the fridge, you will need to pop off the kick panel at the bottom of the fridge by sliding a putty knife between the fridge and the kick panel.

Removing the Drip Pan

Look inside the back or kick panel to find the drip pan, which should look like a small rectangular tray. Grab the drip pan and try pulling it out without tipping it over. If your drip pan can be removed, it will come out of the fridge easily. Empty the pan if it is full of water. You can pour the water down the sink drain or use a wet/dry vacuum to remove standing water.

Cleaning the Drip Pan

To clean the drip pan, you can use a bleach solution (1 part bleach to 2 parts warm water) or a mixture of vinegar and water with a drop of liquid soap. Spray or wipe the solution onto the drip pan and let it sit for a few minutes. Then, use a cleaning rag or paper towel to scrub the pan and remove any buildup or mould. Rinse the pan under warm water to remove any residual cleaner, and dry the pan before reinstalling it.

Reinstalling the Drip Pan

Before reinstalling the drip pan, ensure that it is completely dry. Then, slide the drip pan back into the fridge and replace the panels. If your drip pan is located at the rear of the fridge, you will also need to reattach the back panel and reconnect the water and power supply.

How to clean a non-removable drip pan

The drip pan in your refrigerator collects defrosted ice and condensation from the freezer section, preventing water from leaking onto your kitchen floor. Over time, the standing water can allow germs and mould to grow, causing unpleasant odours. To prevent this, it is recommended to clean your drip pan every three months. Here is a step-by-step guide to cleaning a non-removable drip pan:

  • Unplug the refrigerator: Before beginning, it is crucial to disconnect your fridge from the power source to eliminate the risk of electric shock and prevent any damage to the appliance.
  • Locate the drip pan: The drip pan is typically found at the bottom of the fridge, either behind a kick plate or under the condenser coils/compressor. Refer to your refrigerator's manual to identify the exact location.
  • Remove the kick plate or back panel: Depending on your fridge model, you may need to unscrew or gently pull off the kick plate or back panel to access the drip pan. Keep the screws in a small bowl to avoid losing them.
  • Empty the drip pan: With gloves on, carefully remove the drip pan and empty any liquid contents into a sink or drain. Be gentle to avoid sloshing the murky water.
  • Clean the drip pan: Create a solution of warm water and mild detergent, and use it to clean the drip pan thoroughly. You can also use white vinegar or a disinfecting cleaning solution. Soak the pan in the solution for a few minutes, then use a soft brush or sponge to gently scrub away any stains or residue. Pay extra attention to corners and crevices.
  • Rinse and dry: After scrubbing, thoroughly rinse the drip pan with clean water to remove any soap or detergent residue. Ensure it is completely dry before placing it back into the refrigerator. You can use a clean cloth to pat it dry or let it air dry.
  • Clean the surrounding area: Wipe down the area around the drip pan with a damp cloth or vacuum to remove any dirt or debris that may have accumulated.
  • Reattach the kick plate or back panel: Securely reattach the kick plate or back panel, ensuring a proper fit.
  • Maintain regular cleaning: To prevent mould and unpleasant odours, aim to clean your drip pan at least once every three months or more if you notice excessive buildup.

How to fix an overflowing drain pan

An overflowing drain pan can cause a lot of problems, from water damage to your appliance and the surrounding area to bacterial growth and food spoilage. Here are some ways to fix an overflowing drain pan:

Unclog the Drain Pipe

A clogged drain pipe is the most common cause of an overflowing drain pan. To fix this, you'll need to locate the drainage pipe, which is usually behind a panel on your appliance. Remove the panel and inspect the pipe for any signs of clogging, such as dust, algae, mould, or limescale. If the pipe is clogged, you'll need to clear it out. You can use a piece of wire, a needle, or a slim pencil to do this. Just be sure to clean the pipe thoroughly so that water can flow through it unimpeded.

Adjust the Tilt of the Drip Pan

If your drip pan is tilted too much, it can cause the water to accumulate at one end, leading to overflow. Adjust the tilt of the pan so that it is balanced on all sides. If you need to keep the pan tilted, just ensure that the drain pipe is located at the bottom of the tilt so that it can effectively remove the water.

Replace the Condensation Pump

Some larger appliances, such as furnaces and ducted air conditioners, have a condensation pump to remove excess water. If this pump breaks, it can cause the drip pan to overflow. In this case, you'll need to call a professional to replace the condensation pump.

Check for Improper Installation

Improper installation of the drip pan or other components can also lead to overflow issues. If you suspect this is the case, consult a licensed HVAC expert or technician to inspect and correct any installation issues.

Address Low Refrigerant Levels

Low refrigerant levels can cause evaporator coils to freeze, leading to increased water accumulation and overflow. If this is the issue, turn off your appliance and add the appropriate refrigerant to your refrigerant lines. Also, be sure to check for any leaks, as low refrigerant levels are often caused by a leak. Repairing any leaks is crucial to preventing further issues.

Regular Cleaning and Maintenance

To prevent overflow issues, it's important to regularly clean and maintain your appliance. This includes cleaning the drain pan and line to remove any debris or blockages. Use warm water and a mild detergent to clean the pan, and a long, flexible brush to clear the drain line. Additionally, check the seals on any doors to ensure they are intact and functioning properly, as faulty seals can lead to increased condensation.
