Garrison Oscillating ceramic tower Heater. Model: 043-5931-2
My heater keeps displaying e3 code and beeping at the same time. It does this frequently. I put it on at night to stay warm and it doesn't let me sleep. It used to happen rarely before, but now it has become very frequent. For example, once in 30 min and sometimes 2-3 times in 30 minutes or even more at other times. Sometimes it doesn't beep for an hour. It's very irregular, but consistent enough to be very irritating at night. I can't figure out what is causing it. It didn't used to do this when I first bought it. It's about 1-1.5 years old.
Also suggest better heaters within $20-50 range for a 15 by 10 feet room for sleeping at night. I like the room to be 25 degree celcius.

my electric fireplace is setting level and the heat will not come one. Shows error code 3 and beeps.

I have to have my heater on a slight angle and the E3 code and beeping goes away how do I fix it so I can have it sitting flat on a table to work?? Not angled?

Stabilizing it worked for me. It needed to be on level grounding... I guess the sensors are very sensitive.

The error code and beep is to let you know that the unit may have fallen over. It is a safety shutdown so you do not burn your place down. It seems that some of these heaters are more sensitive then others (my needs to be at a 45 degree angle or better to activate the switch). Make sure that the heater is on a solid level surface like hardwood/laminate floors and not on something like shag carpet.
