Review on Portable Space Heater: Dr Infrared Heater 1500-Watt, Optimal for Efficient Heating by Juan Lockwood

2 weeks worked great. And then he stopped working. I called 1-800 on the heater. The person who answered the call diagnosed the problem as a front circuit board. She said she would send me a new circuit board with instructions. Your willingness to send the board and instructions bothered me; this is not an uncommon problem. The payment came with no instructions. I called again and she emailed me the instructions. The instructions didn't help much, but I figured it out and made a replacement. Now the heater turns on, but that's all it has. Thermostat cannot be adjusted. Well, it works and works and works until we turn it off. You can get heaters with this functionality for significantly less money and without having to completely disassemble them to replace the circuit board.
