I have a Rheem RCFL-HM3617AC 2-Stage Propane Gas Furnace. For the past 8 years we would , when needed, turn the heat up in increments of 2* and it would heat using Stage-1 only. Lately, after turning the heat up 2* it would take 10+ minutes for the heat to kick on. Currently Stage-1 will not produce any heat at all. We turn the heat up 2*, Stage-1 shows on the thermostat but the heat never comes on. Eventually Stage-2 will come on and the furnace will run. Nothing ever happens on Stage-1. No heat, no fan, nothing. I am using a 2-Stage thermostat and the temperatures outside and inside are not below normal.
So I have two questions. 1) Why the change in operation? 2) When Stage-1 shows on the thermostat, even thought the heat never kicks on, does that still mean that gas is being used by the furnace?
Thanks
