How does a gas fridge thermostat work?

Last Updated: 12th May, 2020

42
The thermostat controls the cooling process by monitoring the temperature and then switching the compressor on and off. When the sensor senses that it's cold enough inside a refrigerator, it turns off the compressor. If it senses too much heat, it switches the compressor on and begins the cooling process again.

In this regard, how does a gas fridge work?

A propane fridge has a sealed network of tubes and chambers holding water, ammonia and hydrogen gas. A propane flame heats a chamber holding a solution of water and ammonia until the liquid boils. The ammonia gas rises to another chamber, the condenser, where it cools back into a liquid.

Likewise, can refrigerator work without thermostat? You can run a fridge without a thermostat. A thermostat is nothing more than an on/off switch for the compressor. It goes one when the temp reaches the point you set it at. And goes off, generally, 2 to 3 degree below that point.

Accordingly, how does a thermostat work in a refrigerator?

When the air inside the refrigerator is at the desired temperature, the thermostat stops the flow of electricity to the compressor. When the thermostat senses too much heat, it allows electricity to flow, activating the compressor. In most commercial refrigerators, the thermostat has a capillary tube filled with gas.

Can you smell fridge gas?

Obviously the inside of the fridge will usually smell a little of food - depending on what sort of pungent foods you are keeping inside it - but any other type of smell should put you on alert. Instead, your fridge probably uses another type of gas called HFC-134a, which becomes a liquid at -26.6 degrees Celsius.

Is the gas from a fridge harmful?

Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals.

The limit switch is found only on frost-free refrigerators and freezers. Its function is to keep the defrost heating element from exceeding certain set temperatures. The thermostat control is usually mounted inside the refrigerator. Its visible control knob is turned to regulate the refrigerator/freezer temperature.

Is a refrigerator worth repairing?

Built-in refrigerators are almost always worth repairing. Not only are they less expensive to repair but typically have a longer lifespan anyways. Side-by-side refrigerators should be repaired within a five-year window and considered for replacement after that.

What would cause a refrigerator to stop getting cold?

Vacuum the coils under or behind the fridge. Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won't have a fan). To do this, unplug the fridge and pull it out.
