It runs for a couple of minutes shuts off then restarts 30 seconds later runs a couple of minutes and does this over and over

ANSWER : Most vacuum motors are protected from overheating by a thermal switch that resets after cooling down. Check for blockage in the hose,
.power head or a full bag that would block cooling air from cooling the motor.

ANSWER : Dear Michael_Stad,

I am going to sound like a broken record but here is my same answer to another person with the same problem.

I have I had the same problem with my Dyson DC16, where it only runs for a few.seconds at a time with each trigger pull. My husband called Dyson.(Canada) and without hassle they shipped us a replacement part which I.just received this morning. The replacement part sent to us is: DC16.Main Body with Rating Plate. It is also under warranty for 1 year. The.great customer service makes up for the flaw in the machine. Also,.Dyson is aware of the problem. Hope this helps.

ANSWER : If it runs on NiCad batteries it probably has programmed batteries which can happen, best solution, get new battery, and use til dead before recharge, every time.

ANSWER : Check the filter. If it’s dirty, thoroughly rinse it in cool water, then let it thoroughly dry before using. If you don’t have an extra filter to use during this time, you should get one.
.It could also be a clogged hose or pipe. These would cause the motor to overheat, thus shutting off. Check hose at end for suction. If weak or nonexistent, detach hose and try dropping a penny or dime, or marble, down the hose. If it comes out the end, the hose is probably clear. If this is the case, you need to check other outlets.

ANSWER : Hi its Darran at Dyson.

From your description of the problem, it sounds as though there is a problem with the battery.

Your DC16 will have been supplied with a 2 year guarantee. If it still within this period, please contact our Helpline on 0800 298 0298. However if your machine is no longer covered, a replacement battery can be purchased via our website at www.dyson.co.uk/store.

Kind regards

ANSWER : It’s not necessarily overheating, but the thermal-fuse is definitely tripping and it takes 30 minutes to reset. There are several causes of this (in most common order):
.
.1. A blockage in the suction system or a full dust tank
.2. Dirty filters (Don’t forget to check the air outflow filter at the back)
.3. A worn belt
.4. A faulty thermal fuse.
.5. A faulty motor
.
.As you’ve stated that the dust tank is empty and the filters are clean (don’t forget to check the HEPA / air outflow filter at the rear), let’s look at the other options.
.
.Check the suction is good by putting your hand over the end of the hose and seeing if it will stay attached to you hand upside down.
.
.Next, check the belt isn’t slipping. Lie the hoover on it’s side and check the rollers are turning constantly and at high speed. This isn’t foolproof as it doesn’t account for the extra friction of the brushes on the carpet, but it’s a reasonable test. A worn belt wont necessarily be cracked. It can stretch and slip without cracking. Also, when a belt is slipping, you can usually smell burning rubber.
.
.If the hoover runs ok for 15 minutes and there is no burning smell from the motor, then it’s more likely a faulty thermal fuse than the motor itself. They are replaceable but unfortunately, thermal fuses aren’t always sold separately and sometimes you have to buy a new motor (!!) to get a new fuse. Hoover are one of the best manufacturers when it comes to buying spares, so you might be in luck.
.
.I’ve removed faulty thermal fuses from vacuums because a spare wasn’t available without buying a motor. However, I have always done this with the owners full consent after explaining to them that a safety feature has been removed and they should avoid using the vacuum for prolonged periods without letting it cool. I also test the rest of the vacuum fully before returning it.
.
.If you want to try removing yours, it will be attached to the motor with simple spade connections, but you do this AT YOUR OWN RISK. The danger in doing this is that the motor will burn out if it gets too hot, rather than being switched off by the fuse.

ANSWER : You could have a clog in the hose. Also check your filters, if you haven’t changed them in a while, that could be what’s suffocating your motor
