This tumble dryer is only blowing cold air.I suspect heater element.Has this dryer got a reset button on and if so where would it be mounted?If it is the element is it accessed from the front or the back of the machine.Instructions on how to access the element would be most welcome as no info available.Thanks in advance.

Re: blowing cold air
There is not a reset button on an electric dryer that I know of. If a dryer is blowing air at all, that tells me that the blower assembly and drum motor are working. If you have not heat it is generally caused one of the following:
1. Bad thermal cut-out - located near the heating element housing. Should read a SHORT (0 ohms on an ohm meter) if good. If bad, it is generally a good idea to replace the TCO along with the Hi-Limit Thermostat (mounted right next the TCO in most cases) because the TCO is designed to protect the thermostat and heating element. If the TCO fails, it is likely that the thermostat could also be damaged.
2. Hi-Limit Thermostat failure - located near the heating element housing. The thermostat opens when the internal heat reaches about 157 degrees (on most dryers). This helps regulate the dryer temperature and helps protect the heating element. If it reads a constant OPEN (infinity reading on an ohm meter), replace it along with the TCO (as mentioned above).
3. Bad Heating Element - located under the drum on some dryer models and in the rear on others. The element should read about 9-11 ohms if good. If they go bad, the element will generally burns itself OPEN.
I will need you model number (located near the dryer door opening) in order to give you better advice on how to access the inside of the dryer. Post back with comments and let me know. I hope you find this helpful.
PS I hope I didn't insult your intelligence, but some people are little more saavy than others, so I try to explain things in the simplest of terms.

Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable. On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.) Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.
If your dryer is turning then things are not so bad. If a dryer is not heating then you need to check a few things.
First disconnect the power to the unit. Then you must check the heating element and the limits which are mounted on the heating box.
Remove one lead from the element and check for continuity thru the element. If you have continuity then check the limit by measuring for continuity, again you must remove one of the leads. This should solve your problem
If the drum turns, it could be as simple as a blown fuse or breaker. The dryer has doule breaker or fuses at fuse panel. If the one blows, the heater will not work but motor willturn as motor rums on 110volts. It may be cut out thermostat or could be element, but check the power to the plug of dryer out let and make sure you getting 110 volts on from neutral to both sides and 220 between two live lines.
