I have a Rheem HVAC classic 90 plus that will not light.

Asked Oct 2, 2011, 11:33 AM — 2 Answers
I have a Rheem HVAC classic 90 plus that will not light. I clean the igniter with a piece of sand paper, but it still won't light. The top light of three won't light up neither. I had water go up about 16 inches up from the bottom of the furnace.

You are going to have to give a little more info for me to be able to help much. As far as the lights on the control board, the wiring diagram on the inside of the blower door should give you a code for the led lights that are on the board. Then, if you can tell me what is happening (detailed as possible) when you turn the thermostat to call for heat, then maybe I can point you in the right direction
