Question about Reddy Heater RLP100 Portable Forced Air Propane Heater with Variable Heat Ouput

1 Answer

HVAC heater fan blowing backwards. 480 volt, 3-phase fan motor. Already tried reversing leads, but it always sucks the hot air out the back, instead of blowing it out the front.

Why would a torpedo heater fan turn backwards? every time I start my all pro 115,000 heater the fan starts to spin counterclockwise and the heater wont ignite. But when manually spin the fan blade clo


If the fan has a 'run' capacitor, in rare cases, a faulty capacitor will cause a single phase motor to start in reverse. In most cases a faulty capacitor will cause the motor to only hummmm and not start or start slowly running the right direction then overheat and shut off.

See if there is a capacitor, change it first. If that doesn't fix it it sounds like its time for a new motor.

If you're troubleshooting HVAC electrical problems

230 volt single phase ac
The Common wire or circuit on an A/C or heat pump never has a run capacitor in that line.
The Run wire always has the run capacitor in that line or circuit.

115 volt ac
The Run or Hot wire has the run capacitor and the neutral wire does not.

So if you are tracing wires out in a circuit, if there's a run capacitor, it's the Run wire or Run circuit.
The Start wire always goes to the opposite side of the run capacitor than the Run wire and it is the only wire on that side of the capacitor.
The Run wire goes to the run capacitor, then goes to contactor, compressor, start capacitor or fan, so there's usually two wires on the Run side of the capacitor.

Blower fan not working


you say its in your house and you have 3 phase electric??? Also when the motor was replaced was the motor run capacitor rated to new motor changed also ???

Fi have a older furnace that operates like this. main burners will come on then the blower turns on and furnace continues to heat untill it shuts down on the high limit. there is no blockage on the cold...


Maybe there is a blockage in the air conditioning coil above the furnace? This happens when people have pets, or dont use filters. Single phase 120-240 volt motors won't run backwards if you reverse the wiring that's dc or three phase, you have to check the rotation of the wheel, the right rotation is usually marked on the blower case. Some motors will allow you to change the rotation but you have to check the wiring diagram. Also use new capacitors when they go bad the motor can run backward. God luck

Dayton heater mod 2yu59 is not heating up?


Need to check the low voltage circuit for 24 volts, the 480 volt to 24 volt transformer may have a circuit protection reset or fuse installed. All the 3 phase electric heaters use a low voltage control circuit for operation of relays (24 volt coils).

I bought a Fostoria 3060-3 used heater. My question is can I hitch that up with a 220 line instead of a 480? I might need a manual sent to me(I would pay for one) if no one is sure if that is something...


What you bought is an industrial voltage heater and I purchased one last year as well. According to the manual and the model number you give it translates to 30 kilowatts 60 is 600 volts AC the -3 is three phase. This is only for three phase 600 volt operation, and no you can not wire this heater single phase it will not work period. Even if you do wire this thing at 220 volts single phase double pole there would not be enough voltage to run the fan let alone heat the elements. Can you return the heater? By the way Fastenal is the distributor for these that is where mine was purchased. All of my information is out of the manual that I got with my purchase of a Fostoria FES3048-3.

I am working with a Dayton 2YU39. The name plates states that it has to be powered by 208 volt system. There's a 3-phase panel and a single-phase panel. The 3-pahse panel L1 to ground is 118 volts. L2 is a...


Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

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.

red, white, and black will be your high voltage. Green will probably be for ground and yellow and orange go to the thermostat. I can confirm on Monday when I have access to manuals.
