Won't heat my studio - even on "HIGH"

Have you checked the circuit breaker or fuse for the circuit that your heater is on? It's possible that you had something else come on that, combined with the current draw of your heater, popped the breaker. If that turns out to be the case, turn the heater switch from high to medium or from medium to low so that you're drawing less current.

I''m replying almost a year later, but this may help others who are having this problem. There seem to be a lot of problems with the tip over switch in the Comfort Zone radiator heaters (this is the switch at the very top, inside the panel, above the thermostat). I had the same problem- no heat, switches weren't lighting up. I bypassed the tip over switch (we have never tipped over one of our radiator heaters, so it's not an issue) and connected the switch wires with a wire nut and then further secured the wire nut with electrical tape. Now the heater works as it should again.

when you first bought the heater even if it wasnt "red" as you say did you get heat from it? now those type of heaters are good when they work. First the heater has 2 settings say low and high now in low the wattage will turn some of the elements partly red the reason you dont see it is because it is fan forced heat on those type heaters which causes the elements to look like they are not red but they are on, only low will do this. Now high will cause all elements to get "red" even while the fan is running. If there is no heat someone needs to bypass switch to see if they work.process of iliminitation.Hope this helps for you.

Have you tried resetting the unit?

just push and hold the two buttons on the right for 3 seconds and it will reset.

Or what are the problems you are having with them?
What lights are lit, etc.?

On the comfort zone CZ7007, the #1 rocker switch is for 600 watts, the #2 rocker switch is for 900 watts. If you flip 1 and 2 both to on you will get 1500 watts. Which is 600 and 900 added together. There is no down position, but only on and off.
