For the Vogelzang VG5770 and VG5790 models, we now offer the PCBA control board display and the PCBA control circuit board assembly. We highly recommend a surge protector to be in place at all times to prevent any spikes from damaging the circuitry in your Vogelzang.

Vogelzang pellet stoves will have a high limit switch, low limit switch, and vacuum switch. These are safety switches designed to shut down the fuel feed in the event of an issue. The high limit snap switch will be mounted on the back of the fire wall or up by the auger shaft housing. This is a normally closed switch that will open if temperatures exceed 200 degrees Fahrenheit shutting down connection to the auger motor. This is a manual reset limit switch meaning once the stove cools down you will press the center button to reset the switch. If your convection fan isn't running properly or if your stove is blocked up with ash causing a large lazy fire, this will often cause the high limit switch to trip. You can use a multi-meter on this limit switch to check continuity.

The Vogelzang low limit switch is mounted on the combustion blower housing acting as a proof-of-fire switch. This switch is normally open and closes once it reaches 140 degrees Fahrenheit locking in the auger motor. As the stove is turned off and cools down, this switch will auto reopen at 10 degrees Fahrenheit allowing the combustion blower to shut off. If your experiencing issues with fuel feed after start-up or your combustion blower not shutting down once the stove is cool, it would be advised to look at the low limit snap switch thermodisk.

FOR TROUBLESHOOTING ONLY, we can bypass a safety switch to determine where the issue may be. See our video below on how to troubleshoot switches and sensors with a jumper wire.

The Vogelzang vacuum air switch is also referred to as the pressure switch or low draft safety sensor. The vacuum switch in Vogelzang pellet stoves is sensing pressure in the firebox and exhaust. This switch has a small diaphragm inside that closes when proper pressure is sensed allowing power to go to the auger feed motor. The vacuum switch will have a hose on it that will go to either the firebox rear wall or the combustion blower housing (depending on the year). Inspect the vacuum switch tubing when performing your regular maintenance to ensure there are no cracks or splits. A multi-meter can also be used to test the vacuum switch. Check out our video below for more information on vacuum switches.

If you need a replacement control board, sensor, or switch for your Vogelzang that we don't currently stock, please contact us for information on placing a special order.
