To test the blower motor on its own, you will need a 12V power supply like an RV or car battery. Next, place the test leads to join the positive and negative wires of the blower motor to the positive and negative terminals of the battery. The fan should start immediately. Blower motor...
To make the system work, you set the thermostat higher than the RV’s current inside air temperature, which triggers the furnace to activate the blower motor. Ultimately, if the system functions correctly, the propane ignites, creating hot air that’s distributed throughout the RV through the...
If Blower Motor comes on at R and G, Heating at R and W, and Cooling at R and Y, then the control board can likely be saved. This simple but thorough process is an important step in ensuring that your furnace is operating correctly. Step 6: Test Control Board Output Power Finally, ...
To do so, refer to the electric wiring diagram in section 7. To run the wire properly, refer to the drawings below. Wire running to the control PCB installed on the LEFT side of the furnace Wire running to the control PCB installed on the RIGHT side of the furnace WARNING: USE WIRING...

FIG. 4 depicts a general circuit diagram of the control broad (20) of the present Invention. An electronic timer chip (3) which is located on the said control board controls all the operation of the said emitter and detector, RV1 control potentiometer (7), buzzer 4, and the power LED....
That heavy wire frame may be intended to hold a filter but it'd need a secure mount. Take care: we don't want an air filter to be so poorly supported that it can be sucked into the blower fan - the risk is an overheated motor or even a fire. Also I don't like seeing that ...
The other terminal of the blower motor is connected to a room thermostat 47 comprising a thermal responsive element 48 and an associated fixed contact. The latter is connected to the other side of a source of power through an electrical connection 49. A description of the operation of the...
I did that when my gas furnace blower motor went out, and once the problem was pinpointed, I just got a replacement blower on eBay, found a YouTube video on how to switch it out, and saved $500 over what the pro had quoted me to do the job. Like MMM says, once you open these...
