Our mother came to us and said the dryer was not heating any longer. Of course, when that happens, you drop everything. In the case of this gas dryer–and many others like it, including electrically heated ones–there is at least one thermal fuse or circuit breaker. This shuts the unit down in the case of an air blockage or failed thermostat. In this case, the fuse appears to have died from old age and the time that this dryer spent underwater. Some are self-resetting. Others, like this one, are “one-shot” devices. You replace them after solving the problem that caused the protector to blow.
As it happens, this dryer did go under in a basement flood and was repaired (by me!) afterwards. The only immediate damages were the intrusion of water into the motor bearings and failure of the solenoids on the gas valve. These problems were easily fixed–something to keep in mind if your dryer ever goes underwater. Appliance repair shops may tell you to scrap it, which is not necessary most of the time.
Oh…and no comments on the condition of the room, please and thank you. I’m well aware that it’s a mess.
