  • @Whatasize410a I don't know if bypassing anything on a furnace is a good idea. The manufacturer put in the safeties to protect the end user.

  • thanks dude

  • your so bad!!! stop making videos!! If you do choose to still make videos, try organizing your self and use a white board and dont be so freaking unsure about your shit..and also..dont bother replying to my post

  • @ramirez509 It is possible.

  • @DrZarkloff Yes I have a six point fan relay and the inside blower fan is always on? Once I remove the fan speed wire which comes from the motor it turns off. The fan speed is connected to the normally closed set of contacts i believe its 6 or 5 . Fan relay was switched. I was to it could be the heat sequencers.

  • @maxp8ntballer If you mean 3 poles, you'll need a 3pole single throw relay. You can get that type of relay in the cube type of relay.

    I'd have to know more about the LED setup.
