White Knight gas T/D - heats once then runs cold?

I had a similar problem with my gas dryer, or so I thought.
The problem turned out to be a faulty gas pressure governor (which is located beside your gas meter). It is imperative that the gas pressure is within spec. for the tumble drier to operate otherwise it will keep cutting out. (our gas boiler was not so sensitive and seemed to function ok)

This was diagnosed by a CORGI registered engineer who noticed the gas pressure fluctuating abnormally. He promptly shutdown the gas supply for the house and contacted TRANSCO who replaced the faulty governor within an hour at no charge. Problem solved.

I would recommend that the gas pressure is confirmed to be within spec. prior to diagnosing the dryer - this needs a special type of pressure gauge and I would contact a gas engineer to check this for you to be safe.
