If your Jenn Air dryer light is out, start with the simple checks: the light socket is the most common place to fail, so pull the bulb and use a multimeter to see if voltage is reaching the socket before buying parts. If the socket has power but the light still won’t work, the problem often lives in the control electronics—indicator lights are built into the control panel, touchpad, or user control and display board, and those assemblies must be replaced as a unit. Less commonly, a faulty door switch can prevent the light from getting power, so test the switch for continuity when the door is actuated. A burned or damaged light assembly itself can also be the cause, though it appears lower on the list here. If your dryer controls are not working or the start button is not responding along with the light issue, prioritize the panel and board assemblies.

01 - Jenn Air Dryer Light Socket
If the light itself is newly installed or shows no signs of damage, yet still won't work, it's possible the light socket is defective. You can use a multimeter to test whether or not voltage is reaching the light socket. If the meter shows that power is reaching the light socket then it's likely the socket is malfunctioning and will need to be replaced.

The dryer door switch will turn the interior light off when the door is closed and turn it back on when the door is opened. If the switch is defective, it may be unable to allow voltage to reach the light. You can use a multimeter to test the door switch for appropriate electrical continuity when actuated. If the switch doesn't provide appropriate continuity, it will need to be replaced.
The most likely cause of a dryer interior light not working is a defective light assembly. Inspect the assembly for any visible damage or burn marks and replace as required.
