14 Unexpected flame

What the control is telling you

Flame sensed when the gas valve should be closed. 802P/R95P: amber flame LED blinks rapidly; 1-hour lockout (14 and 10 alternate) that starts once flame is gone. RGPE/RGLE: thermostat also shows Call For Service / CHECK FURNACE.

Applies to: 802P/80MDP (802PA050-150); R95P (R95PA040-115); RGPE/RGLE 2-stage 80+

Likely causes

• Gas valve leaking through or stuck open
• Gas valve relay on IFC stuck closed
• Voltage fed to the gas valve by miswiring
• Heat call (W) not fully removed

Test and repair steps

1. Warning: If flame or gas will not shut off, close the manual gas valve to the appliance BEFORE shutting off electrical power.
2. Remove the heat call and confirm W to C = 0 V at the IFC.
3. Check for voltage at the gas valve with no call; if present, check wiring and the IFC gas valve relay (replace IFC if stuck).
4. If no voltage but flame remains, replace the gas valve.
5. Do not reset until the cause is found.

Settings for these units

Clearance to combustibles (all models) · R95P

Same values for R95PA040 through 115.

Column order read from a rotated drawing header - confirm on the furnace clearance label.

Filter sizes as shipped, upflow (Table 19) · RGPE/RGLE

Use one filter location only - do not double-filter or filter the supply side.

21 in./100K: cut 3-1/2 in. off filter and frame for a side filter; 24-1/2 in./125K: cut 7 in.
