I'm a "pro dickhead". Give me your GPS and I can slap a few knots on
your head, faster than you could rub 'em off.
I spent 25 years dealing with turdheads like you. All mouth!
Is Drexal a school of hard knocks?
As the OP on this thread, I report on closure:
I did install a new vent switch, but that did not really
change the behavior of the furnace. My friend explained the
matter to the landlord, and eventually, for $169, a
technician arrived to diagnose and
fix the problem. He said the "stop" switch was not working,
pointing to the vent switch I had installed. My friend
explained that it was brand new. The technician repeated
that it wasn't working, and added that it was the "wrong
kind". He removed it, added a similar looking switch and
that seems to have solved the problem. I have not had a
chance to get a really close look at the new switch to see
how it is different, but the furnace does seem to behave
Thanks to all who provided help on this situation.
I repair roll laminators for a living...GBC Seal Laminex USI Ledco
Idex, and others..
Always find it funny that customers who tried and failed to fix
something, when told of the real problem say thats not it now fix the
this has even happened with manufactuers who sent me on warranty
thats not it, now fix the problem... they hadnt a clue:(
I have asked them so why did you call me if you knew what would fix
a experienced tech has seen all sorts of wierd troubles, and had to
solve them previously. part of what you pay for repairs is buying that
It's sad that I have to explain to people that the product I sell is
my time, knowledge, expertise and experience, not parts. When a lawyer
hands you a couple of sheets of paper with some printing on them and
says that will be $150.00, there are people who won't bat an eye but
I spend a couple of hours figuring out the intermittent problem they're
having with their latest new whizzbang technowidget and hand them a bill
for $150.00, the same folks will have a fit. There are some people who
aren't charged a dime, like the elderly mother of a friend.
If it's naturally vented (no fan in the vent system) then it's
probably a rollout switch. If so then you have draft problems. Hold
you hand near the switch when the unit starts. Feel hot air? If so
that's exhaust gases that are not going up the vent. If you don't
feel anything then replace it.
Although the problem has been solved, I'd like to know just
what a "rollout switch" does. Can you explain how it works?
I've Googled "rollout switch" but all I learned were places
to buy them, not what they do or how they work. Is it a
switch that does anything more than shut off a circuit if
the temperature sensed by it exceeds a specified level?
Thanks for any enlightenment you can provide.
From what I've read, it appears that the problem was a vent safety
switch which is similar but not the same as a roll-out safety switch.
On a forced air furnace one or more roll-out switches are located
around where the burners take in combustion air and air for the draft.
If the flames "roll out", ie, come out backwards from the burner
assembly, the safety switch(s) detect this and shut down the furnace.
Roll-out switches are usually manual reset like most safety sensors.
