Due to overwhelming response if you have a control
wiring or fan control
I will need as much information as you can provide on what
you have found so far which will require use of a multi tester (meter)
that can measure 24, 120 , 240 volts AC and ohms. For electric
furnaces you will need to check your elements and sequencers which
may require the use of a clamp
on ac ammeter. Like this one being use to check a heatpump current
draw at the contactor.
If you are unsure of your abilities please seek the help of someone who
understands electricity and control wiring. If you have to ask for a place
to start then you really need to seek help. I encourage everyone who is
technically and mechanically inclined to repair their own equipment but
please know when to say when. If you need to ask for a wiring diagram then
you should reconsider trouble shooting your system. In order to read a
wiring diagram you will have to understand electricity anyway.
(fan-won't-shut-off) please review these links and the
links on the home page and here first.
Please DO NOT replace your thermostat as a diagnostic!
To easily see the 24 volt control signal purchase an
1819 light bulb, sockets and clip leads (available at Radio Shack). Connect
the lamp with clip leads (do not let the socket conductors touch anything
else) from the common side of the control transformer to the "W" terminal
from the thermostat or across the gas valve or other 24 volt components
you need to test. This test lamp is one of the most powerful testing tools.
You can fasten the socket to your equipment using a #6 self tapping sheet
metal screw and leave it connected all the time for monitoring purposes.
