how to test a thermal fuse without a multimeter

How to use a Multi-meter to Check a Thermal Fuse. Your first step to testing a fuel pump with a digital multimeter is to test the fuse. The wires leading to the thermal fuse are connected using metal slip on connectors. Remove the wires by pulling on the connectors, and not the wires themselves. Continuity refers to how much resistance there is in a closed electrical current. Follow these steps to replace your dryer's thermal fuse. Normally I'd remove a fuse and test the two connections with a multimeter set to measure Ohms / resistance, but removing this is a non-trivial task - not only is the bolt holding it in place incredibly stiff, it's also holding the wiring together and I don't like the risk of re-assembling the wiring incorrectly or losing one of the many small parts like washers held with this bolt. How to Verify the Thermal Fuse Is Burned out on a Dryer. The beep, an audible indicator, permits technicians to focus on testing procedures without looking at the multimeter display.

This is a safety dev… It is of paramount importance for you to have your multimeter checked and calibrated at least once a year. The next time you try to start the dryer, the motor won't run even though the dryer has power. Testing a dryer's thermal fuse is much like testing its thermostats. A good fuse, for example, should have continuity. Typical example of fuses . Yes No. A thermal fuse is there any way to test without a meter - Answered by a verified Appliance Technician We use cookies to give you the best possible experience on our website. The thermal fuse isn't a current type fuse, so the current value written on the fuse isn't a trip current, but is a minimum carry current. How to Troubleshoot the Thermal Fuse of a Whirlpool Dryer. The thin wire of fuse may be made of aluminum, tin-coated copper or nickel. For an ohmmeter, set it to "Rx1." Easy Ways On How To Test A Fuse With A Multimeter. You need to set the multimeter to continuity setting. Turn the vehicle's key to the "run" position (don't start the engine). A thermal fuse is a small device -- just an inch or two long -- that plays a critical role in preventing fires. Find the thermal fuse at the rear of the dryer, which looks like a flat, curvy piece of metal with a metallic cylinder sticking out of the center. Touch the test light from each fuse's contact to ground. November 6, 2019 rmapplianceparts. You can find it Wifi. Not Helpful 0 Helpful 1. The fuse can be checked without a meter by removing the two wires and joining (jump) them together. Community Answer. Take the red and black probes attached to your multimeter and set them on the 2 thermal fuse switches. Put in a new fuse as soon as possible, and don’t run your dryer in the meantime! A blown fuse, therefore, is often an indication of an overloaded circuit or a fault such as a short that is causing excessive current flow in the circuit. Also, I have a Duo. Step 1 Turn off the power supply to the appliance or other electrical device if the device is hard-wired. Some places mandate that the fuse be in the power plug, but my USA model doesn't appear to have one there. 5. Connect the multimeter's black probe to a ground point. Test light method: Turn the ignition on (to energize more circuits).
