My bush tdv6w vented tumble dryer is not heating up
If your dryer is an electric dryer, it is sounding like you have either a bad heating element or one of the two limit switches are open. The limit switch is an "overtemp" device to shut down the element if it gets too hot from air restriction. Lint build up in the blower and ducting is a major cause of restricted airflow across the heating element. Excessive tripping of the limit will result in an "open" limit switch and continual failure to generate heat. There should be one limit switch built into the heating package and the high limit will be located on the drum usually near the top, though there are some near the bottom of the drum as well. Any attempt to find and replace must be done with the power off as you are dealing with 240 volts.
If your dryer is gas fired, you've had a misfire probably due to a defective hot surface igniter or bad control module. Unless you are fairly capable of learning as you go, and have the basic tools for troubleshooting you probably need to call a sevice technician.
