<!-- from fixya rte -->Hz-709 turns on ad off on its own - Honeywell HZ-709 Oil Filled Radiator Heater

Was there any physical damage to the heater when it fell over?

The HZ-709 has safety features that might prevent its subsequent operation.
1 - It has a tip over switch but the heater should operate normally when it's upright again.
2 - A thermal cut-off fuse will permanently shut down the heater should it operate at a higher than normal temperature. Was it operating when it fell over, or could it have overheated?

If it's none of those, try contacting the manufacturer Kaz directly by email, Facebook, Twitter, etc. as the HZ-709 has a 3-year warranty.

Have you tried calling Honeywell? http://www.honeywellstore.com/store/products/honeywell-hz-709-oil-filled-radiator-with-electronic-controls.htm

I am having the same problem. I am not sure the cause but I was reading that some manufacturers will put automatic shut off switches in the electronics. I read that it was mainly printers and faxes but I wonder if that could hold true here as well?

let sit overnight, most likely disturbed the internal t-stat.The oil has to settle again. And make sure power oi off before turning on.

Check the anti- switch.the plumer is stuck in down position. Ken's Repair

chelk the mains cord,chelk the voltage in the heaters element if no then chelk the heat aduster(thermostate) if current is available on element then your element is burnt replace it.

Is there a seperate control for the timer and temp? If so, turn the temp off first and then the timer.I think they need each other for safety.
