If your roaster is not getting hot enough here are a couple of things to check before contacting us with an issue.
The supply voltage is critical. If you have a way to measure voltage, I would suggest doing so. Just 1-2 volts too low and your machine will only hit temperatures of 400* -430*. We like to see a starting voltage of 120-122. Then with the base plugged in and the fan and heater on, only a 4-volt drop. Anything below 115V will make it really hard for this machine to get up to temperature. So no extension cords or any other appliance stealing power that the roaster can consume.
The next thing to look into, the fan speed throughout the roast. If you run the fan on 9 the entire roast the air is being blown out before it has a chance to be trapped by the beans. We like to start with the fan on 9 and slowly back the fan down as the beans get lighter in weight as this can help the roasting temperature. We are looking for a nice rotation of the beans, similar to a soft boil.
Another factor in roasting is the ambient air temperature. Around 55* it can make it difficult to get enough heat out of the roaster.
