Infinite ohms means that the part will not allow electritity to go through it. Another word for this is "open". An ohm meter can tell you if a part is good or bad while the machine is unplugged. It's a very handy tool if you're going to repair your own machine. It is not necessary to spend a lot. I've seen them for as low as $2.89 at Harbor Freight Tools.

To test a part, use an ohm meter on the terminals of the part. You'll need to disconnect one wire from the part (to avoid misleading readings) while making the test. Be sure to replace the wires after each test. Nearly all the parts will measure less than one ohm. The heating element should be about 8 or 10 ohms. A failed part will measure "open" (i.e. the reading you get when the meter leads aren't touching anything.)
It may help to pull out the tech sheet, usually under the console. It shows the path for current from L1 to N through the heating element. You will need to test only those parts in this path.

I recommend checking the thermal fuse first. Its location depends on which dryer you have, but it's always near the blower wheel. If you need more help, I'll need to know your dryer's brand and model number (almost always inside the door.)
Good luck!

Sounds like the thermostat is either defective or has a bad connection. If you are familiar with using a multimeter (volt-ohm-current meter), it would be the device to use to trouble-shoot this problem. MAKE SURE THE HEATER IS UNPLUGGED!!!

With the meter set on Ohms, and the heater set on auto, set the heater to its lowest temperature setting. You want to see no resistance (close to zeor Ohms) when check across the thermostat (the temperature knob mounts on it). If you see high or infinite resistance, the thermostat's open and therefore defective. If the thermostat checks out OK, continue checking with the meter. You should have about zero Ohms between the hot pin on the power plug (the narrower one in N. America) and the heater motor lead. If it's open (high or infinite resistance), keep the one meter lead on the power plug and trace back, checking each connection until you find the defective one. Don't rule out a broken wire, maybe inside the insulation (but unlikely).

Checking a fuse I get .4 ohms for continuity does that mean I will get 1.4 for a bad fuse cuz that is what is happening. If the contacts are connected I get .4 and when they are not I get 1. When I

You cannot check ohms with circuits that are connected together. Also with electronic circuits it is not recommended to do continuity tests with the meter as you could damage these. Also depends on what type of fuse you have. Please provide make and model of dryer and which fuse component are you looking at. Someone who is familiar with that model might be able to help.

Kenmore 300 dryer runs but does not heat

With the dryer off, use a volt/ohm meter and see if the heating element has resistance. If there is infinite resistance the element is bad. If the element tests OK, check the thermisters. They are usually button shaped parts that shut off the heat if it gets too hot. These and fuses need to be replaced if they have infinite resistance. Generally, these blow when you have lint build-up and the air can't flow.

The dryer doesn't blow any heat 11074972300

Check heating element with Ohm meter should read something.
Infinite reading means the coil has burnt out. replace.

I have a gas dryer not heating properly. it heats up for about 15 seconds then stops heating for about 15 seconds and continues doing the same. i ohmed out my cutoffs and stats and fuse. all good. im...

Does the actual flame come on or just the igniter? if flame comes on I would start be disconnecting the vent from the dryer and then running dryer. If still the same problem you can rule out a vent restrictiion problem. If its just the igniter coming on with no flame then check your burner coils on the gas valve. They should check less than a couple K ohms. A bad coil will read infinite ohms.

Kenmore dryer no electricity

First check the power to dryer from the wall and then make sure the wires on the dryer are still tight and there is also 220 to 240 volts AC to dryer. Next check the door switch, which could either be broken or has just stopped making contact. Unplug all power before taking anything apart. The console and the top will need to be removed to get to the door switch. The switch should measure 0 ohms when the door is closed and no reading or infinite ohms when the door is open. Next, there is a fuse on the blower housing, remove the bottom front panel and the fuse is on top of the blower housing, usually white in color, and oblong in shape. This fuse will fail if the dryer overheats so clean the vent in the home thoroughly. With the age of the dryer these fuses sometimes just fail with age. The fuse is a thermal fuse and should measure 0 ohms or close if it is good and no reading or infinite ohms if it is bad. One of these should take care of your problem. Your model number should be 110.87983100. Thermal fuse is part number 3390719 and retails for $16.35 Sears has it for $17.40. The door switch is part number 279782 retails for $28.58 but sears has it for $18.57.

No heat. The dryer functions on all cycles, just no heat. Model #11062622101

dryer is built by whirlpool, unplug ,remove back, check for resistance of element with an ohm meter. if reistance is infinite ,buy another element part #279838. if not check the thermostat above the element , should read 0 ohms

Dryer works fine, but does not heat up. Is it the

Good day,
You will need an ohm meter to check the heating element. It should show only a few ohms of resistance.
With the back removed, you will see many small devices, mostly round and all should read zero ohms.
Pay particular attention to a long skinny white bakelite device in the center. It causes more failures than all the others combined. It should read zero ohms as well.

Two terminals stick out of the bottom of the cannister on the right side. These are the terminals for the element itself.

If all check, O.K. Check to see if you have 230 volts at the Plug.
Careful, that stuff can kill.

If the element checks open, then follow the instructions below.

The dryer runs but no heat, a maytag.

1st make sure CAREFULLY (if this is a normal elec dryer), you're getting 220 to unit.(sometimes 1 of 2 circuit breakers have gone bad). Next, UNPLUG UNIT, I cant stress this enough.
Wiring diagram should be in unit, usually in behind control panel.
While performing following tests also very carefully check all wires and connectors. You have at least 1 thermal sensor probably 2 (different types). Ohm these, at ambient should read very near 0 ohms. These read infinite at predetermined high temp. Ohm across heating elements, correct is very low resistance.

Kenmore 80 series Heating Problem

Most of these issues will need an ohm meter, unless you want to just take a guess.
For Gas dryers.
1. See if the ignitor glows, if not, check the thermal fuse. (if the lint screen is on top, the fuse is accessed behind the back panel, it's small and white, next to the bulkier thermostat. If the lint screen is in the front panel, the thermal fuse is mounted on top of the blower wheel housing, accessed behind the bottom-front or "kick" panel. The fuse should read 0 to .2 ohms at the most, technically is should be zero. If that checks ok, check the ignitor itself, which has a wire harness that connects about 6" from the ignitor. Should be around 50 ohms... a faulty ignitor would read infinite ohms (open).
2. If the ignitor does glow, and you hear a click, but there is no flame, replace the valve coils, (two small cylindrical objects mounted on the valve) Part # 279834. This is assuming your gas is ON.

If Electric, it would not be the fuse, as on electric dryers it is also in the motor circuit, and the dryer would not run at all. Check the heating element, should be around 9-11 ohms. If good, check all thermostats (operating, hi-limit, thermal cutoff). Infinite ohms is bad. Hopefully it's not more complicated than this, or it can get weird..... Hope this helps.
