I have a client with a Tru-Blu quattro 90 furnace made in 1995. Someting keeps kicking blocking the signal to the gas valve. I have identified it to the pressure switch, a double acting unit. Unfortunatly, my vendors cannot find one of the type I have discussed and they cannot find Tru-blu. No one hear has heard of it. Dou you know of a vendor that had/had carried this brand? Also, i dont't believe the problem is the switch, but nothing else jumps out at me. It is intermittant, but I need a little help.
Thanks,
Jeff

Have not heard of that brand before but you should be checking the inches of water with a manometer and make sure it is the same as the rating on the switch. Let me know if you can give me any more info.
Be careful sometimes you don't get a second chance

Their is no label on the switch. A quick puff of air down the hose sometimes resets it. I think i have moisture entering the diaphram of the switch. My vendor is shipping all pressure switches they have so I can find one that may work.
Thanks for the info.

Quatro is a Consolidated furnace. They no longer exist.
