"BadHtr" This is as close as we could get to writing "Bad Heater Circuit"
IF YOU HAD THE COOLBOT OPEN TO REPLACE A DIFFERENT WIRE CHANCES ARE THE WIRES ARE NOW PLUGGED INTO THE WRONG PRONGS ON THE CIRCUIT BOARD. There is tiny lettering on the board identifying the different prongs, the top prongs are for the power cord, the next is for the room sensor, the second from the bottom is for the frost sensor and the heater wire (all heater wires made in the last 5 years have red shrink wrap on the tip.) The color of the plug is random.
If it's not a wire in the wrong plug a BadHtr message could be from one of four things:
- Water: If moisture got into the CoolBot then that could cause a short out. Use a hair dryer to dry out the board.
- Corrosion: If there was moisture that got in there and caused some corrosion on the connection points than that would interfere. You can try cleaning it off.
- Goo: Somehow, if some sort of film found its way into the CoolBot and got onto the connection points it would make for a bad connection. Try unplugging and plugging the heater wire a couple times to work it off or unplug it and wipe off the connection points.
- Damage to the tip of the heater: Check the end of the heater to make sure that the insulation on the end of the CoolBot heater isn't melted, torn, chewed on, etc.. If it is, you can put one layer of electrical tape on the tip and call us to purchase a replacement heater wire at 888-871-5723.
After cleaning up and drying out the CoolBot, unplug and replug the power to the CoolBot.
If it still says BAD HEATER, then that means the damage is on the board and unfortunately it cannot be repaired and you should contact us. You can either call us at 888.871.5723 or email at firstname.lastname@example.org
