Dose nothing when plugged in and here's a pic

Hi @caseyteska

If you have a DMM (digital multimeter) use its Ohmmeter function to check for continuity in the hair dryer, by placing the Ohmmeter across the two pins on the power cord plug (unplugged from the power outlet) and switch the hair dryer on.

If all is OK you should get a resistance reading on the meter as it is measuring the path from the power cord plug, through the switch, and through the heater element in the dryer.

If there's no resistance measurement showing on the meter then there's an open circuit in the operate path of the dryer.

You will need to open the dryer and start doing point to point testing from the power cord plug and through the dryer to find out where the problem is.

With the dryer opened place one meter lead on a power cord plug pin and then find where the power cord wires terminate in the dryer and check if the wire is OK, then do the other pin in the plug and check that the other wire in the cord is OK from plug to dryer. If both wires test OK then you know that the problem is not the power cord. Next follow a wire from the power cord wiring terminals in the dryer to the switch and then prove that the switch works by proving continuity through the switch when it is operated and so on to the heater element etc.

Apologies if you already know how to do point to point testing using a DMM.
