How do I find the model of my Maytag refrigerator?
For your Maytag MZD2665HEW side-by-side refrigerator, the model number is printed on a rating label inside the cabinet. Check the fresh food section first, then the freezer and door frame areas if you do not see it right away.
Most common places to look
- Interior ceiling of the fresh food (refrigerator) compartment
- Inside wall of the freezer compartment
- Inside of the refrigerator door
- Door frame (around the opening)
- Interior wall behind the lower crisper drawer
- Either inside wall of the cabinet
- Interior floor bottom (remove the crisper drawer to see it)
Quick steps that work on this model
- Open the fresh food door and scan the side walls and ceiling for a white or silver sticker.
- Pull out the lower crisper drawers and look behind them and on the bottom floor.
- Check the freezer side wall and the door frame if you still have not found it.
- Write down the full model number and serial number exactly as shown.
What the label usually looks like
| What you will see | Why it helps |
|---|---|
| Model number (example: MZD2665HEW) | Matches the correct parts diagrams and replacement parts |
| Serial number | Helps identify production details for service and compatibility |
| Electrical ratings | Useful when troubleshooting power, lights, or compressor issues |
Why it matters
We use the exact model number to match the right Maytag refrigerator parts (ice maker, light switch, evaporator fan motor, door gasket) and to ensure the instructions and diagrams line up with your cabinet layout. For model-specific label locations and diagrams, use the MZD2665HEW owner's manual.

What is a side-by-side appliance?
A side-by-side appliance (for the Maytag MZD2665HEW, a side-by-side refrigerator) has two full-height vertical compartments: the fresh food section on one side and the freezer on the other. This layout commonly supports in-door ice and water features and easy access to both sections.
How a side-by-side refrigerator is laid out
In a side-by-side design, both compartments run from top to bottom, so you do not have to bend as much to reach freezer items.
Typical layout features include:
- Refrigerator section on the right; freezer section on the left (common, but not universal)
- Tall door bins for beverages and condiments
- Freezer shelves and door bins for boxed and bagged items
- In-door ice and water dispenser on many models
- Separate temperature controls for fresh food and freezer
Side-by-side vs. other refrigerator styles
| Style | What it looks like | Best for |
|---|---|---|
| Side-by-side | Two vertical doors, fridge and freezer next to each other | Balanced fridge and freezer access, narrow door swing |
| Top freezer | Freezer on top, refrigerator below | Simple storage, usually lower cost |
| French door | Two fridge doors on top, freezer drawer below | Wide fridge shelves, large platters |
Why it matters when buying parts or troubleshooting
The side-by-side layout affects airflow, door sealing, and ice and water routing. When we help you choose parts for the MZD2665HEW, we match components to the correct compartment and feature set (for example, dispenser parts vs. freezer cooling parts).
Common side-by-side related service areas:
- Ice maker and dispenser performance
- Evaporator fan airflow between compartments
- Door alignment and door gasket sealing
- Temperature control behavior and operating sounds
Where to confirm features on your exact model
Your feature set can vary by series and production run, so we recommend checking the MZD2665HEW owner's manual for the exact compartment layout, temperature control details, and ice and water operation.

How to replace the water filter in a Maytag side by side refrigerator?
On the Maytag MZD2665HEW side-by-side refrigerator, the water filter is in the upper right corner of the fresh food (refrigerator) compartment; remove it by turning it counterclockwise, then install the new filter by inserting it and rotating clockwise until it stops, and flush water for 2 minutes to clear air.
Step-by-step: replace the water filter
- Open the refrigerator (fresh food) door and locate the filter housing in the upper right.
- Turn the old filter counterclockwise until it releases.
- Keep the filter upright, drain it into a sink, and discard it.
- Wipe up any water in the filter cover/housing.
- Remove the sealing label from the new filter, insert it into the filter head, then rotate clockwise gently until it stops.
- Close or snap the filter cover (if your unit has one).
Important tips (to prevent leaks and splashing)
- Use caution when removing the filter; trapped air can cause water and the cartridge to eject.
- After installing the new filter, run water continuously for 2 minutes until the flow is steady.
- Expect a 1 to 2 minute delay the first time you dispense water; the internal tank needs time to fill.
- If you see black specks at first, it is normal carbon dust from the new cartridge and clears after a few uses.
- Replace the filter at least every 12 months; sooner if water quality is poor or usage is high.
Flush and performance checklist
| What you notice | What it usually means | What we recommend |
|---|---|---|
| Water spurts or sputters | Air in the water system | Flush 2 minutes at the dispenser |
| Slow water flow | Low pressure, kinked line, or clogged filter | Check supply valve fully open; replace filter if needed |
| Leaks at/near filter | Filter not fully seated or O-ring not sealing | Reinstall filter; rotate fully clockwise |
Why it matters
A properly installed, regularly changed water filter helps maintain steady dispenser flow and reduces common ice maker and water dispenser problems caused by restricted water flow.
For model-specific illustrations and the exact filter location details, follow the MZD2665HEW owner's manual. For additional Maytag-specific tips, use our how to replace the water filter in a Maytag refrigerator guide.

What is the average lifespan of a Maytag refrigerator?
Most Maytag refrigerators, including the Maytag MZD2665HEW side-by-side, typically last 10 to 15 years. With steady maintenance (cleaning, good airflow, and quick repairs), it’s common to reach the upper end of that range and sometimes longer; use the MZD2665HEW owner’s manual for model-specific care routines.
What affects refrigerator lifespan the most
- Condenser cleanliness and airflow: dust buildup and tight clearances make the system run hotter.
- Door seal condition: air leaks force longer run times and can cause frost and temperature swings.
- Ice maker and water system upkeep: mineral buildup and leaks create avoidable wear.
- Temperature settings: overly cold settings increase run time and frost risk.
- Fast response to symptoms: unusual noises, warm temps, or water leaks should be addressed early.
Maintenance checklist (high impact, low effort)
- Vacuum dust from the grille and condenser area (frequency depends on pets and dust).
- Keep vents inside the fresh food and freezer sections unblocked.
- Confirm doors close and seal evenly; clean gaskets with mild soap and water.
- Replace water filters on schedule and flush the dispenser after changes.
- If cooling seems weak, check for evaporator fan noise and steady airflow.
Common “life-extending” repairs on this style of refrigerator
| Symptom | Likely area | Example part for MZD2665HEW |
|---|---|---|
| Warm fridge, freezer OK | Air movement from freezer | Evaporator motor WPW10128551 |
| No ice or intermittent ice | Ice maker assembly | Refrigerator ice maker D7824706Q |
| Lights stay off or act erratic | Door/light switch | Refrigerator light switch W11396033 |
Why it matters
A refrigerator’s compressor and sealed system last longest when the unit runs efficiently. Simple items like clean airflow paths, good door seals, and stable temperatures reduce run time and heat stress, which directly supports long service life.
