How to Test a Thermocouple on a Gas Valve Here's how to test a suspected thermocouple in a gas operated water heater: Light the pilot by pressing and holding the pilot light button on the gas control valve. If you can't light the pilot, the problem most likely lies with the gas contr...
Test the gasket on a freezer door with the same dollar-bill procedure; if the gasket is faulty, replace it with a new gasket made especially for the freezer. Do not remove the freezer door to replace the gasket. Freezer doors are often tensioned with spring devices, which can be very tro...
Once the lint trap is clean, turn off and unplug the dryer. If you use a gas dryer, close the shut-off valve in the gas supply line, then disconnect and cap the line pipe before cleaning. Then, you’ll want to pull out the dryer for easier access to the vent duct. To clean the...
If you were to touch this part of the system, you'd feel it change from hot to cold. The high-pressure liquid refrigerant flows from the receiver-dryer through the expansion valve, where it is allowed to expand. This expansion reduces the pressure on the refrigerant, so it can move into...
From safely washing a sleeping bag to measuring partially used gas canisters, here’s how to look after your hiking gear
and the refrigeration capacity was insufficient. If the dryer or expansion valve is clogged, and the clogging is yellow-brown wax-like or black sludge-like foreign matter, it is recommended to extract the refrigerant from the system for purity testing to troubleshoot the risk of inferior refriger...
Check for water flow: After closing the valve, turn on the faucet to see if the water supply has been successfully shut off. If no water comes out, then the water supply has been properly turned off. It is important to note that in some cases, the shut-off valve may not completely ...
A chest freezer compressor is part of a system designed to freeze food to keep it from spoilage. The compressor circulates the refrigerant gas to raise its pressure and temperature. The heat is then dissipated inside the Condenser coil, then cools down some through the expansion valve before re...
Receiver Dryer: Removes moisture from inside the system to prevent rust and corrosion. Expansion Valve/Orifice Tube: Releases high pressure refrigerant gas into the evaporator. (Each part does basically the same thing, though an expansion valve can vary the amount of refrigerant passed through it ...
If a patch fuse has been used, some traces can be found, such as scratches on the fuse, deformation, or breakage of the fuse. If so, it is necessary to carefully check whether the fuse was caused during transportation or if it was used before. By learning to distinguish fuses, one can...
