Top 10 Appliance Parts to Replace Before Winter

Winter in New Zealand can be cold and wet. Most families stay indoors more. Appliances work harder. The fridge keeps food fresh, the oven cooks warm meals, the dryer dries thicker winter clothes, and the heater runs day and night.

Small parts can break because of the cold. A hose can crack. A belt can weaken. A seal can leak. These issues can make your power bill high or cause damage.

Good winter appliance maintenance helps your home stay warm, clean, and comfortable during the cold months. It keeps cooking and laundry running smoothly, lowers repair costs, and supports safe gas and electricity use.

In this guide, you will find the top 10 essential appliance parts for winter and why they matter. You will also learn when to replace them, how to care for them, and the signs of winter damage to look out for. Every home in New Zealand can follow these easy steps to stay prepared and protected throughout the winter season.

Which appliance parts should be replaced before winter?
Replace water filters, fridge door seals, oven heating elements, stove igniters, washer hoses, dryer belts, dishwasher spray arms, HVAC filters, heater thermostats, and fireplace or heater remote batteries. These items support winter appliance maintenance and keep homes warm, safe, and energy-efficient in New Zealand.

1. Refrigerator Water Filter

Clean water is important in winter. People often drink more warm drinks. Soup, tea, and coffee come from filtered water.

Why replace before winter

• Removes rust, dirt, and germs
  
• Makes ice clean and clear
  
• Protects inside fridge pipes
  
• Helps the fridge work with less pressure
  

Dirty filters force the motor to push harder. This increases your power bill.

Signs to replace

• Bad smell
  
• Cloudy water
  
• Filter light is red
  
• Water flow slows down
  

How to replace

• Twist filter left
  
• Pull out
  
• Put the new one in
  
• Run water for 2 minutes
  

Care tip

Mark your calendar. Replace every 6 months.

This is one of the most purchased kitchen appliance parts NZ shoppers order before winter months.

2. Fridge Door Seal (Gasket)

Cold air should stay inside. A weak seal wastes energy and spoils food.

Why it fails in winter

Cold air makes rubber stiff. It cracks faster.

Easy home test

Do a simple paper test:

• Close a paper sheet in the fridge door
  
• Pull it
   If it slides out easily, the seal is loose.
  

Replace signs

• Door pops open
  
• Frost inside
  
• Food spoils quickly
  
• Seal looks dirty or has gaps
  

Care tips

• Clean seal weekly with warm soapy water
  
• Do not push heavy items against the door
  
• Keep the fridge level
  

A fresh seal means more savings on power bills.

3. Oven Bake or Grill Element

Winter means comfort food. You may bake pies, pizzas, and slow-roast meals.

Why replace before winter

• Old elements heat unevenly
  
• Cooking takes longer
  
• Higher power usage
  

Signs of damage

• Burn marks
  
• Bright spots on the element
  
• Uneven baking
  
• Smoke when heating
  

How to care

• Turn power off before checking
  
• Clean the oven but keep cleaners away from elements
  
• Do not bend the element
  

Many homes in NZ upgrade oven parts early to enjoy warm meals every day.

4. Stove Igniter

Gas stoves may struggle in wet and cold weather.

Danger of faulty igniters

Gas comes out but does not light right away. That creates risk.

Warning signs

• Too much clicking
  
• No flame on first try
  
• Flame drops low during cooking
  
• Gas smell
  

Care steps

• Keep igniter area dry
  
• Remove food spills quickly
  
• Use a soft brush for soot
  

Safety reminder

If you smell strong gas, turn the stove off and call an expert.

Replacing this part is a key step in winter appliance maintenance.

6. Washing Machine Hoses

A sudden hose burst means water everywhere. This happens more in cold months.

Why replace

• Rubber gets stiff in winter
  
• Hot water cycles create pressure
  

Danger signs

• Rust at joints
  
• Bulging shapes
  
• Cracks
  
• Leaks on the floor
  

Care tips

• Stainless steel hoses last longer
  
• Replace every 3–5 years
  
• Check tightness monthly
  
• Keep laundry room warm and dry
  

This small step avoids big repair costs.

7. Dishwasher Spray Arm

Winter cooking = more dishes. A weak spray arm cannot clean well.

Warning signs

• Hard food stuck to plates
  
• Cloudy glasses
  
• Dishes still wet
  

Care tips

• Soak spray arm in vinegar
  
• Use dishwasher cleaner once a month
  
• Check spinning movement
  

A good spray arm saves time and water.

8. HVAC Filter / Heat Pump Filter

Heat pumps work the hardest in winter.

Why replace

• Clean warm airflow
  
• Less dust in home
  
• Faster heating
  
• Lower power bill
  

Signs of clogged filter

• Air feels weak
  
• More noise from heat pump
  
• Room takes long to warm
  
• Dust smell
  

Care

Replace filters every 4 weeks in winter for the best heat.

This is a must-do task in every home appliance parts NZ checklist.

9. Gas Heater Thermostat

A heater that guesses wrong temperature wastes power.

Warning signs

• Too hot or too cold
  
• Heater turns off fast
  
• High power bill
  

Care tips

• Keep area clean from dust
  
• Change batteries yearly
  
• Check if screen is clear
  

A working thermostat means comfort and safety.

10. Heater or Fireplace Remote Batteries & Sensors

A weak remote can stop heating when you need it most.

Signs to replace

• Buttons do not respond
  
• Screen fades
  
• Delayed actions
  

Care

Keep fresh batteries ready before winter.
Check if any white powder shows near the battery area. Clean gently.

Check Outdoor Units Too 

Winter weather hits outdoor machines harder.

Check these:

• BBQ ignition button
  
• Outdoor fridge seal
  
• Heat pump outdoor unit (clear leaves)
  

A tidy and dry outdoor area protects everything from corrosion.
