Edenpure has a troubleshooting guide at this website: MY HEATER WILL NOT TURN ON.

• Make sure the power source is good. Plug in a lamp to see if it works correctly.
• Make sure the front power switch/button is set to the "ON" position.
• Unplug the power for 30 minutes. Plug the power back in and try operating the heater again. This will reset the internal sensors.
• Some heater models are designed to be operated in temperatures less than 75 degrees Fahrenheit. The heater will not operate when the temperature is too high. Test the heater in a room that is below 75 degrees Fahrenheit.
• Bring the heater inside to warm up for at least one hour before operating if it has been stored in a freezing or near freezing environment.
• Make sure the filter is clean.
• Remember, it will take a few minutes for the heater to warm up. The fan will start to blow after the heater has warmed up.

Heaters FAQ

there are two very small screws just above the on/off switch. Once you unscrew those two, you can use a knife (carefully) to lift the on/off panel out of the air filter. I just did this. My problem is now that I don't understand how the on/off button is supposed to work at all.. there was no spring or anything I can see that could have pushed the on/off button back up. I am considering just leaving the actual button out and pushing the microswitch directly. Looks like bad engineering to me.
