Fan on my big buddy heater just stopped working changed batteries still not working?tried the switch nothing .i only have radiant heat.
I would first check the wiring connections to fan and get a multi meter , set on 12 volts dc and see if fan motor has 12 vdc input voltage.
Too cheap to buy a voltage tester at wal mart ot harbor frieght, you can use a 12 volt bulb and socket, if you already have one. Remove fan wires & hook up 12 volt light bulb & if it lights, you got the juice. Carefull,dont let live wires touch because you short out $26.00 big buddy fan transformer. work with fan transformer unplugged from wall and dont plug in until you sure no wires touch.
use electrical or duct tape. electrical tape better.
otherwise,just buy the multi meter, they only $8.00 to $10.00
read & understand instructions, before you try to use it. otherwise,you could burn out your new meter.
well worth owning &
learning to use multi meter. I use it thousands of times.
if fan motor has juice but wont run, check fan shaft to see if it turns freely or scrapes or is stuck. oil fan motor bearings ,change the brushes.
make sure that the fan blades are not touching the fan housing and can turn freely.
if it still dont work, buy new fan motor.
if no juice at fan motor, check mr heater switch with the power off,unplug transformer from the wall or remove batteries.,
and use the ohm meter setting of the multi- meter to test for continuity of the switch when the switch is in the on position.
power must be off when using the ohm setting of a multimeter.
if power is on & using the ohm setting of the multi meter, you will blow out the multimeter. The ohm setting uses a 1.5 volt dc battery inside the multimeter to test for a compleated circuit.
so, 12volts dc would blow it out on ohms setting.
TESTING FOR OUTPUT OF FAN TRANSFORMER OR BATERY PACK.
If the switch is good,reinstall it on mr.heater and test the output of the transformer or battery compartment using the 20 volt dc scale of the multi meter. the voltage scale you select ,must be higher than the voltage you expect to find ,in order to avoid damage to the multi meter.
observe polarity,positive to red and negative to black.
the dc voltmeter setting is totally polarity sensitive and a reversed hook up could blow out the meter.
multi meter means it can read ac volts, dc volts,ohms and dc amps. Read and understand the included instructions before using a multi meter
a good single battery in new condition reads 1.62volts dc
1.5 vdc is almost dead, a good used battery reads 1.58 to 1.6 vdc
below 1.58 vdc is weak battery and 1.48 vdc is usually totally dead, but may be enough for momentary usage under 1 minute.
