Hiya Unless its a direct drive.. would suggest your belt has slipped, or snapped...

When the drum is turned by hand can you feel a slight resistance?

Gas and Electric Dryer Troubleshooting & Repair.


The following procedures will help you repair your dryer whether it is gas or electric. While doing any resistance checks on the unit make sure it is unplugged as you will be exposed to lethal voltages if the unit is not dieconnected. Additionally when doing resistance checks remove one wire of the circuit, replace the wire when done. The best place to get parts for any appliance, best price and availability, is at http://www.repairclinic.com .

Electric dryers are probably the most common so I will address that first. If the unit spins we know it has power. Move to the next paragraph. If it doesn't spin check the receptacle for 120 vac. If you have it. check the door switch for continuity. Remove the top to access the switch. Using a DMM, on resistance scale, depress the switch and see that it has no resistance. If this checks bad (high resistance) replace it. If good access the start switch. This may require removing the control panel from the top of the unit. While engaging the start switch check for continuity. If open, replace it.

The most likely culprit, when the unit spins but does not heat, on an electric unit, is the heating element. Once used they get brittle and any moving around can crack them. With the unit unplugged remove the back. Should only be several screws around the perimeter. Some units have an inspection plate which can be removed to access the element. Using a DMM on resistance, check the continuity of the coil. It should read several ohms if good. If it reads infinity, you need a new heating element.

If the coil checks OK you will need to check the limit switch. It is located somewhere in the vent area and shuts the unit down if it overheats. Many times these bimetal switches stick open. It looks like a hocky puck mounted to the vent. Once located remove at least one wire and check for continuity. It should have no resistance. If it has a high resistance it will need to be replaced. This should solve your problems if you have an electric dryer. Either the heating element, door switch, start switch or the limit switch will be bad.

If you have a gas dryer the resistive coil is replaced by a gas burner which is a little more difficult, and dangerous, to troubleshoot. If it is less than ten years old it should have electric start. Open the inspection door on the bottom front and see that when you call for drying, (start it), the igniter sparks. If it doesn't and it obviously has power the igniter box will need to be replaced.

If the igniter works and you know that you have gas (other gas appliances work) and the gas valve on the dryer is on, then the control valve has a problem and will need replaced. This may be a job for a professional as working with gas is dangerous and you should be qualified to do the repair.

Beyond those two items there is a light sensor in case the flame doesn't start or goes out. This shuts the gas valve but would only be a factor in the repair if the units burner lights up, runs for a minute and shuts down. It is a photo cell located in the area of the burner.

There is also a tempreture sensor but this would only be a factor if the unit heats but not to operating level. It is similar to the limit switch on an electric dryer and the same troubleshooting applies.

With the above information you should be able to repair any dryer on the planet. Good luck.

Dryer has 110V only.Light burns when door is opened.Controle panel does not switch on at all.Each leg where power cord is attached has 110V.I have replaced Thermal Cut-off & High Limit...


Hi,
Your problem is not in the dryer. 220V circuits can be confusing in that the 110 leg can feed back and in reality you are getting the same 110V reading on both legs. Check across the two legs and see if you get 220V if not then you have confirmed what I suspect. Your problem is probably with you circuit breaker in the electric panel. Try switching the breaker off and forcefully turning it back on, You also can take off the panel cover and check to see if you have 220V across the two poles of the circuit breaker. You may have to replace the circuit breaker, it is not uncommon for one leg of a breaker ot go out especially when used on a dryer that pulls high amp. resistance loads.

Dryer will not heat up.


The following link can give you some more advise on troubleshooting a dryer no heat problem:

http://www.fixya.com/support/r630242-dryer_runs_but_not_heat

Begin by verifying your input voltage at the wall receptacle. You should read 220-240 VAC across the two hot leads (the left and right slots in the receptacle). If good, remove the back cover over the terminal block of the dryer (where the power cord is installed) and plug the dryer back in. Take a reading across the RED and BLACK wires at the terminal block. If good, your problem is in the heating circuitry. If bad, you have a bad power cord.

The reason I mention the input voltage is because many people assume it is good if the dryer drum is still spinning. The drive motor which turns the drum, however, only uses half the input voltage because it runs off 110-120 VAC. The heating circuits require the full 220 service in order to operate. If you are missing a portion of the source voltage, the dryer will exhibit the same problems you describe.

Read through the link I provided and pay particular attention to the section that discusses proper dryer ventilation. Most dryer heat related problems are actually caused by poor ventilation causing the dryer to overheat to the point of failure. If you haven't cleaned your ventilation ducting anytime recently, now might be a good time. Leaving a dryer in a clogged or poorly ventilated condition will cause repeated failures of any components you might be replacing.

If you have questions along the way, let me know. I hope you find this information helpful.

GE dryer barely heating


If this is an ELECTRIC dryer, you're supposed to read 120VAC at both L1 and L2. With the cord UNPLUGGED, check the voltage across L1 and l2 at the wall receptacle. You should read a cumulative of 220-240VAC. If you're only getting 120VAC, the problem is at your receptacle, which would explain why the dryer is not heating. The heating circuits and timer require 220VAC, while the drive motor only requires 120VAC. If the power at the receptacle is good, leave the dryer unplugged and check the continuity of the power cord from the end of the plug at L2 to the terminal block at the back of the dryer. You should read a short or 0 ohms. If the continuity of the plug is good, the problem may be a loose connection at the terminal block or a broken wire. If the continuity is bad (open), then it looks like you may have a bad power cord. Please post back if you have questions. I hope this helps you.

Dryer won't start


hi,
1) Be sure your clothes dryer is plugged in and turned on. If necessary, check the receptacle it's plugged into for power, using a working lamp, appliance, or voltage tester. Be aware that most electric dryers don't plug into standard 120-

volt receptacles; they operate on 240 volts. 

Make sure the door is closed completely, the timer is advanced to the proper position, and the correct cycle is selected.

2) If the receptacle is dead, check the circuit breaker or fuse that serves that circuit.

3) Unplug the dryer and check the power cord and the terminal block. If necessary, replace the cord.

4) Open the door, and check the door switch. Press and release it; it should click each time. If it doesn't, it's probably broken.

If you're experienced at home repair, you can remove the switch, test it, and replace it if needed; otherwise, call an appliance repair service.

5) If the dryer still doesn't work, a thermal fuse or other electrical or electronic part may be faulty. The thermal fuse, found in the back cover panel, can stop working if the dryer overheats. Call an appliance service person if you suspect an electrical part may be malfunctioning.

Maytag Neptune MDE7500AYW - Won't start - Message says "A power failure..


I had the same problem. It turned out a power transformer in the neighborhood had gone bad. I found it by checking power at the receptacles in the house and we weren't getting proper voltage throughout the house. We had enough power in the house to power lights, the TV, coffee maker etc. but not enough for the dryer. I called the power company and they came out to do a check. At first they said there was a wiring problem with the house until all the neighbors started coming over after seeing their vehicle and saying they were having problems. So maybe you aren't getting proper power to the unit.

Good luck. Hope this fixes your problem.

Neptune Dryer PF Error Code


PF is a 'Power Failure' code meaning the dryer power may be interrupted. The plug receptacle may be bad. Check the plug for proper tension. If feels loose, have the receptacle replaced. Inspect the plug for discoloration. (a sign of a bad receptacle). If all looks OK, Check the power connections at the dryer. If looks OK the electronic control may be defective.

Oasis dryer 67086


PF is a power failure fault. This indicates that a power failure occurred while the dryer was running. You can press START to continue the cycle or PAUSE/CANCEL to clear. Have you had any storms lately, or power outages? If you haven't, and this continues to be a problem, you may have your receptacle checked to ensure that you have the proper voltage at the outlet (roughly 220-240 VAC). If you notice the plug or receptacle as burned you may have a loose wire causing the problem. The wires at the terminal block of the dryer should also be checked to make they are tightened properly. Unplug the dryer before attempting. I hope this helps you.

If necessary, replace the cord. 4) Open the door and check the door switch. Press and release it: it should click each time. If it doesn't, it's probably broken. If you're experienced at home repair, you can remove the switch, test it, and replace it if needed; otherwise, call an appliance repair service. 5) If the dryer still doesn't work, a thermal fuse or other electrical or electronic parts may be faulty.
