Hotpoint nvl333gyoww gas dryer's timer stopped working and ran for an extended length of time (about a day). After looking over the dryer, i noticed that during the no heat cycle the timer would work. So I started the regular heat cycle; after five minutes i checked the cycle and found that the dryer was heating the clothes. So, I came back an hour later to find that there was no heat once again. Could you help me identify the problem? Thanks.

The timer : if you use time dry the timer should always move and complete the cycle. if you use auto dry the timer uses a sensor to tell the timer to move. If your not getting any heat your sensor might not tell the timer to move.

So lets start with the no heat problem. First make sure your Vent is clear or just disconnect the vent and put a pair of womans stocking over the end to keep the dust down, This will ensure you do not have a blocked vent. ((( If you have a blocked vent on a gas dryer the safty sensor will shut off the gas valve and you will only get a little bit of heat))) Now try the dryer for small load, ((( if this solved your problem then you have a cloged vent )))

If this did not solve your problem then the coils on your gas valve in the dryer are probably bad.
