Customer Question

I have an EB17B Coleman A/C - Furnace.. I have been having problems with my furnace fan stopping at random times while my outside unit runs.. I have changed my thermostat, blower motor, and capacitor. And that still hasn't fixed it... I'm not sure where to go from here.

Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.Do you have a volt meter for troubleshooting? It sounds like you may have a bad blower relay.What we need to do is see if we are getting 24 volts to the coil on the relay when blower is not running and should be.Then check for high voltage into relay and out of relay.
If we are indeed getting the 24v to relay coil, but not getting high voltage through it to motor the relay is the issue.

I will have to get a volt meter and try it...

OK I am going to send a diagram.
See the links below:
On call for cool, we should have 24vac between coil terminals and 240 volts between orange power wire and terminals 2 and 4
