Gas Patio Heater Troubleshooting

NO POWER TO HEATER  
CAUTION: Before performing any service or maintenance work on the unit:  
a) disconnect the electrical supply  
b) shut off gas to supply unit  
c) make sure the unit has cooled down before opening the service panel  

INITIAL ELECTRICAL CHECKS  
a) Make sure the thermostat is calling for heat.  
b) Make sure the electrical connection is secure.  
c) Check electrical supply for blown fuse or breaker.  
d) Test for power to the burner head.  
e) Check wiring to components.  

INITIAL GAS CHECKS  
a) Make sure the manual valve is turned on.  
b) Make sure the gas valve knob is turned on.  
c) Check for gas supply and proper pressure to the valve.  
d) Check wires and make sure that they and their connections are in good condition.  
e) Check for power to the valve.  
f) If no power, check the control board.  

ELECTRICITY AND GAS TO HEATER, BUT STILL INOPERATIVE

A) Mis-wired  
B) Transformer bad  
C) Fuse/circuit breaker bad  
D) Bad control (check LED for steady on)  

Thermostat on - No Blower Output

B) Bad thermostat - Do voltage @terminal W  
C) Bad control (check LED for steady on)  

Pressure Switch input okay but no trial for ignition after purge delay  
A) Mis-wired (check PSW terminal voltage)  
B) Flame sense problem (existing flame-check LED-2 Flashes)  
C) Bad control (check voltage between L1 & IND)  

Valve on, no spark  
A) Shorted electrode  
B) Open HV cable  
C) Bad Control  

Spark on, no valve  
A) Valve coil open  
B) Open valve wire  
C) Bad control (check voltage between V1 &V2)  

Flame okay during TFI, no flame sense (after TFI)  
A) Bad electrode  
B) Bad S1 or HV wire  
C) Poor ground at the burner  
D) Poor flame (check flame current)
