All the Mill Convection heaters (with exception of AB-H700MINI and JA-series) have a lightning symbol on the heater indicating if the heater is generating heat or not. The heater should generate heat if the lightning symbol is lit.
If the heater for some reason does not heat when the lightning symbol is lit, it is likely that there is a problem with your Mill heater. To troubleshoot if the heater is defect or not, please do the following routine:
- Reset the heater (except AB-H700MINI and JA-series)
- Set the heater to maximum temperature (35 degrees Celsius). (For JA-series set the heater to MAX)
- Within 5 to 10 minutes your heater should be warm. You can control this by holding you hand over the top of the heater.
- If the heater does not get warm you can contact the store where you bought your heater to get further help (please remember to bring your receipt).
If the heater does heat and everything seems to be in order, you need to calibrate the heater so that it gets adjusted to the room its located in.
