The heating element in a gas dryer and heating coil in an electric dryer use. So be sure to check the air path inside the dryer as well. Test the continuity of the thermal fuse with your multimeter by placing one. There is also the possibility that if you have a bad lint screen in the dryer or were operating without one in place that lint can build up right inside the dryer air flow path and cause overheating even though the venting may be fine. Do be aware that the overheating event could also have been caused by a lint capture screen in the dryer being clogged up and not being cleaned before every load is started. I know you said in comments that the vent is clear. If you feel that the high temperature cutout has opened up due to age or a one time overheating event then it should be OK to replace it with a new one and start using the dryer again. Something caused the cutout to open circuit and this is then causing the heater coils to not get any current to create heat.
The fact that you do not see any change in the reading when you check across the high temperature cutout indicates that this is the faulty component. Your meter appears to read a 1 in the left most digit when the meter is detecting an open circuit.
TEST DRYER HEATING ELEMENT HOW TO
The 000 reading for the thermostat indicates that the thermostat is a closed switch at room temperature and is a strong indication that this component is OK. How to test heating element in dryer in summary Just use an ohmmeter to check the resistance(of the element)- The element is probably bad if it is an open circuit. It could be a vent line that got crushed, a vent line clogged up with lint, an outside vent screen jammed with lint or even a snow bank that blocked off the vent outlet. After you replace the faulty component it will be necessary to determine why the dryer may have overheated in the first place. If it shows a high reading or an open circuit then you have located the faulty component.īe aware that there is a good probability that the dryer may have overheated and caused one or the other of the thermostat or the high temperature cutout to go to open circuit. If you use your OHM tester you should be able to place your probes across each of these and read a low reading of just an ohm or two (not more) for each one. This video demonstrates how to test a heating element on an electric dryer.
TEST DRYER HEATING ELEMENT SERIES
The most common wiring for a dryer is that the thermostat and high temperature cutout fuse are wired in series with the heater element and so you may be able to find them by tracing the wires that connect to the heater element. How to test heating element in dryer Now, if none of the coils appear broken, you should use a multimeter to test the element for continuity. Often times such diagram is located pasted onto some panel of the dryer unit. To check the other components you will have to locate them in your dryer by using common sense and any electrical diagram you can find for your dryer.
So your reading of 8 or 9 ohms is not unrealistic and probably indicates that the heater element is not burned to an open circuit. It would be normal to see a few ohms of resistance in a cold heater coil.
