Tempstar Gas Furnace - Inducer Stopped Working

So... I was here almost exactly a month ago and I had an issue where the inducer motor would not shut off (original thread HERE. I got excellent help and banged on the relays to get it working again....

Today we notice its a bit cold in the house... We discover that the furnace now has the 3-blinking light trouble code (low pressure switch is off when should be on).

Basically the inducer motor is not turning on so that the whole system will function.

Any way I can make this guy work till monday when we can get a HVAC guy here. I plain cant make the service call on sunday....

Thanks in advance!

Oh.... Second thing came to mind. Friday when I was putting my shoes on for work I heard the inducer motor start then stop. then start then stop....

Could it be the LP switch? Im going to get one now... we shall see.
