Updated September 2026 • Clearwater, Pinellas County, FL
If your fridge still smells after you've thrown out old food and wiped the shelves, the odor is usually coming from a dirty drain pan under the fridge, a clogged defrost drain holding stagnant water, mold in the door gaskets, or an old water filter or ice bin. After a power outage or a summer shutdown, mold in the insulation and liners is common in Clearwater's humidity.

Hidden Sources of Refrigerator Odors
| Where | What causes the smell | Fix |
|---|---|---|
| Drain (drip) pan under the fridge | Defrost water plus dust and spills sit in the pan and grow bacteria | Pull off the bottom grille, remove and wash the pan if accessible |
| Defrost drain | Clogged drain holds dirty water behind the back panel | Flush with warm water; persistent clogs need service |
| Door gaskets | Mold grows in the folds in humid weather | Scrub with warm soapy water; replace if stained deep |
| Ice bin and ice maker | Old ice absorbs odors; mold in the bin | Empty, wash the bin, discard the next 2–3 batches |
| Water filter | Overdue filters can give water and ice a musty taste | Replace every 6 months |
| Crisper drawers and seals | Produce juice pooled under drawers | Remove drawers and clean underneath |
Step-by-Step Deep Clean
- Empty the fridge and throw out anything expired.
- Remove shelves, drawers and bins; wash in warm soapy water.
- Wipe the inside with 1 tablespoon of baking soda per quart of warm water. Avoid bleach on gaskets.
- Scrub the door gaskets, including the folds.
- Clean the drip pan and flush the defrost drain if you can reach it.
- Dry everything fully, then leave an open box of baking soda inside.
After a Power Outage or Summer Away
If the fridge sat off with the doors shut during a hurricane outage or while you were away for the summer, mold can grow on liners and in hidden spaces. Clean as above, then leave the doors open for a day. If a musty smell returns after cleaning, moisture may be trapped in the insulation or drain system; a technician can check the drain, pan and seals. See our snowbird checklist for how to avoid this next time.
When a Smell Means a Repair
- Water under the crisper drawers plus a sour smell: clogged defrost drain. See water leak repair.
- Burning or electrical smell: unplug the fridge and call; it can mean a failing fan motor, relay or board.
- Chemical smell: older fridges with a refrigerant leak may smell; newer R-600a units have little odor. Ventilate and call for service.
- Food spoiling fast: the fridge may be running warm. Check with a thermometer; it should be 37°F.
Odor Prevention Routine
| How often | Task |
|---|---|
| Weekly | Toss expired food; wipe spills the same day |
| Monthly | Wipe gaskets and shelves; empty and rinse the ice bin |
| Every 3 months | Replace the baking soda box; clean crisper drawers |
| Every 6 months | Replace the water filter; clean condenser coils and the drip pan |
Why Florida Fridges Smell More
Warm, humid air carries moisture into the fridge every time the door opens. Moisture plus food residue is what mold and bacteria need. Defrost water also sits in the drip pan under the fridge, where the warmth of the compressor area speeds up odors. In Clearwater's muggy season (April to November), the same fridge that stays fresh up north can start smelling within weeks.
Myths That Don't Work
- Bleach on everything: it hardens gaskets and can leave a taste in food. Use baking soda and mild soap.
- Air fresheners inside: food absorbs the scent. Remove the source instead.
- Turning the fridge colder: slows bacteria but doesn't remove mold already there.

Frequently Asked Questions
The odor is often from the drain pan under the fridge, a clogged defrost drain, mold in the gasket folds, or the ice bin and water filter, which a normal wipe-down misses.
Empty it, wash all parts with warm soapy water, wipe the inside with baking soda solution, clean the gaskets and drip pan, dry fully, and leave the doors open for a day.
It can be. Unplug the fridge and call for service; a failing fan motor, relay or control board can overheat.
