Re: Coleman 7956-856 burner won't light

I have a Honeywell RTH2310B, a programmable heat/cool thermostat which can be jumpered to support a two-wire system. Just today I flipped the switch on the relay box to 'cool' and while the flame indicator is on on the thermostat display, the condenser outside was running and the furnace was pushing...

Probably doesn't matter two months later, but yes it does.

Re: Coleman 7956-856 burner won't light

I came back here to poke around and my post is still the first on the list so I thought I'd update the story. Replacing the gas valve, although bad, didn't fix it. On subsequent visits the A-coil was cleaned to be sure it wasn't so dirty it was blocking airflow and overheating, and the final frustra...

Re: Coleman 7956-856 burner won't light

Had a chance at having a service guy come today so I took it. He was very good, checked the gas pressure, voltage everywhere, airflow everywhere and just plain visual troubleshooting. He measured the the pressure at 5.4wc and watched the valve open irregularly, if that's a proper word. Voltage at th...

Coleman 7956-856 burner won't light

Our Coleman 7956-856 natural gas furnace has an intermittent burner lighting problem. The thermostat clicks, the furnace clicks but burner does not light. Pilot is always lit. We had a tech out maybe six weeks ago for this problem, he said the valve orifice had spider junk in it, cleaned it and it h...

RE: Evcon condenser fan not running, possible capacitor

Just so I understand, it was the round one I'm having trouble with. Does it not need both?

Thanks for the info, I'll be ordering soon.

Evcon condenser fan not running, possible capacitor

We have an Evcon Model BRQC036B condenser outside the house. I believe the problem is with (one of) the capacitor(s). One of the mounting prongs on the capacitor seems to like to burn itself off a couple of times each summer. I clean the wire, put on a new female end and reattach and everything's fi...
