3. Troubleshooting
Note: Testing is done with the blanket disconnected from the power source.
o Check your power supply and extension cords, etc. to ensure that they are working properly.
o Check your blanket for damage: puncture holes, rips, cuts, tears, nails, staples, form spikes or
melted/deformed spots.
o Check the electrical resistance characteristics of your blanket using an ohmmeter. To do an ohmmeter test
follow steps 1-4 below.
1. Disconnect the plug/cord of your blanket from the power supply.
2. Inspect the plug and cord for signs of damage. Do not use your blanket if it has a damaged plug or cord.
If it is not damaged, please continue with the troubleshooting.
3. Connect the ohmmeter to the blades of the plug on the blanket (Ref. image 1C). Compare the meter
reading with that shown on the cord tag of your blanket (Ref. image 2C), (It should be that value +/-
10%). If it is too low, there may be excessive moisture within the blanket or the heater may have been
damaged. If it is too high, your blanket may have been damaged.
4. There should be high electrical resistance from the ground post to either of the blades on the plug of
your blanket. Connect the ohmmeter from the ground post to one of the blades (Ref. image 3C). Note
the reading. Then, connect the ohmmeter from the ground post to the other blade on the plug. Both of
these readings should be greater than 75,000 ohms (75 KOHM). The higher the better. A low reading
indicates that your blanket has been damaged.
