heater mats under tanks
How to know your heater mats are working under the tanks? Our switch is on and the lamp is on, But there seems no heat.
I'm hoping to not to disassemble anything

- A clamp-on ammeter will tell if the current flow is within specs. Often there is a thermostat right at the heating element. Depending on temperature you may need to place an ice pack right on the thermostat to close the switch.
- There is nothing to tell you the pads are on. The light being on just tells you power is available to the pads.

Most, do have an internal tstat in the pad. The way I test, is to take a can of PC air and turn upside down to freeze the area where the wires enter the pad(where the tstat is). I then wait a few minutes and shoot the actual pad with an IR thermometer to make sure it is heating.
