Heat4Less/HomeComfort Infrared Heaters

Trouble Shooting

1. Power indicator light and temperature display come on, but heater doesn’t come on.
Replace rear board. (video# R3.1)

2. Heater runs then shuts off, beeps and turns back on. This happens over and over: 
Fan is running too slow or not at all. Replace fan, or Replace heat sensor. (Video R6)

3. Plug in heater and nothing happens: 
Replace over heat sensor first (Video R6) or rear board. (video# R3.1)

4. Everything works except fan.
Replace rear circuit board first (video# R3.1) or fan.

5. Green light above power button doesn’t stop blinking.
Replace one of the 4 bulbs that is not working. (Video #R2). 
If all 4 bulbs are working, replace rear board. (video# R3.1)
Green light blinks, one or no bulb comes on, replace rear board. (video# R3.1)

6. Displays E4.
Replace rear board. (video# R3.1)

7. Displays E3. 
Replace thermostat probe

8. Top bulb and fan stop working, other bulbs stay on.
Replace trunk wire.

9. Smells like something is burning.
First: check the end of the power cord where it plugs into the wall outlet. If it looks like burnt… There is arcing and the outlet or plug is bad or the wire inside the wall is old or too small in size.

Second: Plastic is melting above hot air grill exhaust because the fan is running too slow or not running at all.   

Third: A stink bug has died inside heater. The smell will eventually go away or you can remove one side panel of heater and shake until one or more bugs fall out. 

1. Flashing E3: 
New thermostat probe or new 6 strand trunk wire. 

2. Everything works except fan: 
Replace 6 strand trunk wire between both circuit boards. 

3. No Power, just switch on back of heater turns on: 
Replace switch or Replace circuit board. 

4. Heater won’t run but front instrument panel lights up: 
Replace 6 strand trunk wire. 

5. Push on/off button on front of heater and top bulb goes off but the rest stay lit and heater keeps running: 
Replace circuit board. 

6. Everything works but can’t adjust front panel buttons: 
Unlock board by holding up/down arrows at same time until beep or Replace front circuit board. 

7. Green light above power button doesn’t stop blinking.
This is normal. This just means that the heater is running. 

8. Heater is running then bulbs turn off, fan keeps running for 3 minutes. At the end of 3 minutes the bulbs and fan turn back on. This keeps happening every few minutes.
Nothing is wrong. This is the 1 degree cycling. Check video #8
