I have an older janitrol heat pump 240 volt.

The compressor runs at 240. That doesn't mean the control circuit
does. It's probably 120.


It's more likely the control circuit runs at 24V, which is
what the transformer is for.



I know my transformer is bad.
However it's an older one with one 1 black wire built in. The rest of the
wires connect to it with spade clips.

If you expect to find a transformer with the same wires and spade
lugs, you might find one at a furnace supply store, in person or on
the web, if you provide the furnace make and modle.


Given that this transformer apparently isn't a garden variety one,
and he doesn't know what he's doing, getting the identical replacement
one is a good idea.


Otherwise you'll be wasting your time to look for wire connections
that look like you have now. The wire connections are not what
matter. It's the primary voltage, the secondary voltage, and the
output amperage available that matter.

The one black wire plugs into power
supply. Another red wire comes from power source and plugs into
transformer. On the other side I got a ground wire plugged in, another
wire plugged into a relay of some sort, and 2 more wires plugged into the
t-stat wires. New t-stats have 4 wires coming off one side. I'm assuming I
use those 2 for power coming in. Cap off other 2. On other side I have 2
wires coming off at 24 volts

So are you saying that the secondary of the transformer is putting out
24 volts?

Bingo.

If so, on what basis do you say at the top that you know
your transformer is bad?


Presumably the 24V isn't there, but who knows how he determined it.
Maybe smoke is coming out.
