SOURCE: Blinking lights. Shuts off.
Hello, Mne was also shutting down. Turns out that is was clogged with dust, therefore overheating and turning it self off.
If you're handy, you may want to open the heater and dust it off with a can of compressed air.
Worked for me.

Dust on the inside of the unit can cause the overload switch to shut many vornados down. Blowing the dust out of the unit with compressed air or a blower may help.
Another problem that causes vornados to stop working (light on - no heat no fan) is when one of the bearings starts to go bad in the unit. This causes the fan to be slower and less effective and the unit’s inability to move the heat away from the thermal overload switch again causes it to shut down.
Though you could remove the front and rear bearings and try to get replacements if it's even replaceable ... Once the bearing starts to go bad there is little that can be done ... HOWEVER, here is one solution to get more life out of the unit.
First, use a blower to blow all the dust out of the unit.
Then, because it is typically the front bearing that goes bad first, lay the vornado on it’s back (so the unit would be blowing air up toward the ceiling), this will relieve the front bearing somewhat and rely more on the rear bearing which tends to last longer.
The vornados I’ve had are all thermistor units ... that is, they don’t just turn on and off when the set temp is reached but in fact slow themselves down (both heat and fan) to keep some level of air circulation in the room. This is a good thing by the way.
There are usually two toggle switches .... one is a heat switch - usually Low & High .... the other is the thermistor switch (this sometimes is labeled “fan”) - usually Auto & High.
Once the unit is on its back ... Now, change the settings as follows:
Turn the Heat switch to LOW
Turn the Fan switch to HIGH
Turn the dial (with the temperature in degrees on it) to the lowest setting - which is somewhere around 60’ish.
Now turn the unit on and it should stay working.
Three things that could cause it to turn back off ...
You turn the Fan switch back to Auto.
You turn the Heat switch back to High
You turn the temperature selection dial too high ... though, you can cautiously turn the dial up a few degrees at a time ... the unit will start shutting down again when you set the temp too high ... then just dial it back down ... unplug for a couple minutes, then turn back on.

take the wattage of the heater, divide it by 1000 then multiply that by your cost per KW/hr from your electric bill, then multiply that by the number of hours you operate the heater. That will give you the exact cost to operate at full heating per hour.

sounds like either a bad thermocouple or more likely a pressure regulator problem. should have unit checked by someone familiar with propane systems.

Is there a frost line on your LP tank, if so you may need to replace the tank with a larger tank or refill your tank. This can happen if the tank your using is too low or too small (use 100 lb tank or greater). If there is no frost line it may be an issue with the thermocouple. The manufacturer offers a service manual and owner's manuals on there site. This should assist you... www.desatech.com Thank you
