Which home appliances have thermostats in them?

Updated: May 17, 2023

When you hear the word thermostat, you probably think of the thermostat on your wall that controls your furnace. We think of the heat cable systems we install to prevent snow and ice buildup. But did you know that many appliances have a thermostat in them? Are you wondering which ones? Well, a few of our readers have answered that question. Clare Ivatt is the founder of

More Than Just the Obvious

It’s amazing how many home appliances have thermostats when you think about it. There are the obvious ones like a washing machine and dishwasher, which use a thermostat to control the temperature of the water, but how about the ones you wouldn’t suspect?

Here’s a little list just to begin with: fridge, freezer, oven (gas and electric), kettle, drip coffee maker, sandwich maker, electric blanket, hairdryer, curling tongs, electric radiator, toasted sandwich maker, electric grill, slow cooker, and a fan heater!

Almost All Appliances Have a Thermostat

When thinking about home appliances with thermostats in them, a few such as refrigerators, ovens, water heaters, and air conditioners may come to mind easily. But many people are surprised to find that a lot of other appliances, such as coffee makers, crock pots, dishwashers, laundry machines, and hair dryers, also have thermostats.

Almost all appliances have a thermostat of some type to ensure that they stay within safe temperature ranges for their intended purpose.

Thermostats play a more important role in appliances than people may realize. Many of the appliances we use every day wouldn’t be able to function without having a thermostat in them to help regulate the process. Rachel Lee, VP of Sales, Whynter LLC.

Any Appliance That Heats or Freezes

Generally speaking, every home appliance that produces heat or freezing power uses a thermostat. Ovens, irons, toasters, microwaves, freezers, air conditioning systems, clothes dryers, and coffee makers.

Without the thermostat, these gadgets will be useless. For example, a freezer with a broken thermostat won't turn the compressor off. As a result, the temperatures will get so low that the tubes will freeze. If the same happens to an oven, it might burn the food because nothing is telling the heating system to stop working.

Hairdryers and Glue Guns

Essentially all appliances that create heat or cold temperatures have thermostats in them. This includes more obvious appliances like furnaces/ACs, ovens, refrigerators, dryers, toasters, crock pots, hotplates, and coffee makes.

It also often includes less obvious appliances like hairdryers and glue guns. Appliances like these require thermostats so that they don’t go below the lowest temperature they should go, or above the highest temperature they should go. This is necessary not only for their functionality but for their safety as well. Kristen Bolig, CEO, Security Nerd.
