Hello,
My Carrier 58mvp Gas Furnace has suddenly started intermittently firing. There is plenty of gas pressure at the valve but will continue to run constantly without too much heating properties. There is a flame in each of the burners. Could someone please explain what the flame sensor does and how it functions? The error code that was diplaying at times were error code 34 (ignition proving failure) All troubleshooting remedies were used according to the manual given and were all proven good. This is an intermittent problem and works for a day or so then will not fire. Then suddenly will start but see weakness in the burner flames. Then once again it will fire and work as supposed to. Any suggestions w/out having a service call.
Thanks in advance.
Doug
