heater stopped working

I have an older furnace RHEEM RGDD-10NCAJR that stopped working last night. We usually had in on 68F, and it worked fine for all winter. We were expecting guests, therefore set it little higher to 70F. It worked for some time, then stopped, and this morning we found out it never turned ON again, as temp inside the house was 58F.

Thermostat is set on HEAT, 62F right now. I hear humming noise inside the furnace. Voltage between C -R and C - W is 27 volts. Any ideas what might be wrong?

Thanks in advance for all help!

Take the cover off the burner compartment.

Turn the thermostat down, then up again to turn on the furnace.


Carefully observe the sequence of events that occurs and describe that sequence here.

There was misconnect in wires. I touched various cables that lead to ignitor and it lighted up! Whoo hoo!
