Pilot light lit but no heat

When trying to fire up my patio heater the pilot light lights but goes out when trying to turn gas supply knob to either high or low heat. Is there a way to find out if the thermocouple is shot. It has been cleaned, used compressed air.

    I dissasembled the main gas valve/regulator and think my thermocouple is not holding open the plunger after the pilot is lit. Any suggestions?

    I have a similar problem. I turn the **** and press it. The ignitor works and the pilot lights up but does not stay lit. I have to try this several times (15/20 times). Sometimes it does not light up at all. It's done this from day one so cleaning the venturi is not an issue. Am I doing something wrong?

The pilot's millivolt generator may be at fault.  if you have a meter that is capable of measuring a very small DC voltage, connect it up to the very end of the thermocouple and the copper cappillary. the thermocouple has a welded bead at the very end inside that generates a small DC voltage. Same principle of a J-K thermocouple. Iron constintan  - two dissimiller metals where joined together produce a voltage when heated.  the thermocouple actuates a millivolt electromagnet inside the valve to keep the valve pellet open.  no voltage there it won't actuate the electromagnet.

The pilot light is on but the heater will not come on. We have a programmable thermostat and it shows temp etc.

This is the most common question and issue around these heaters. The Pilot Assembly needs to be cleaned out. See steps 7 through 14 here.

    If this has done it from day 1 make sure the thermocouple is tight in the back of the valve. It is very common for it to become loose during shipping. Unfortunately you can't just buy the thermocouple for the Endless Summer of Blue Rhino. You have to order the complete pilot assy.

Need to light pilot light

You need to turn the knob on the gas valve (inside the heater) to the "pilot" position. Then, while holding a flame over the pilot assembly push down on the knob.

Gas should come out of the pilot and ignite. Continue holding the knob down for 10-15 seconds. Release the knob and the pilot should stay lit. If not the pilot generator may need to be replaced.

Turn the knob to the "on" position, close the heater and turn the heater on and turn the thermostat to hot. The heater should fire. If it does not fire and the pilot goes out, that may also indicate a pilot generator problem.

Hi, If the pilot light goes out when you turn the gas knob to full power on lighting them the most likely cause will be a worn thermocouple, these usually last between 2 years up to 6 years. Found this site very helpful, patio heater problem solving. They have a few solutions to checking patio heaters.

There is a thermocouple that detects that there is a pilot flame so that main gas won't come on unless there is a pilot. That thermocouple is faulty. These are available from a plumbing supply house. The thermocouple will be attached right in the flame from the pilot and connects back into the gas valve.

The system works off of a thermocouple that is heated by the pilot. The thermocouple creates millivolts that magnetize a head behind the control knob. When you push in the knob the magnetized head behind the knob holds the gas valve open. So obviously the head is not being magnetized. First make sure that the pilot is not plugged and the flame is large enough to heat the thermocouple. Also sometimes you may need to hold the knob for several minutes before the pilot will stay on. Also patio heaters have a safety feature that will cut the millivolt circuit if the heater falls over. It is possible that this safety device is tripped or defective causing the pilot to not stay lit. Also check for any loose wires on the millivolt system.

You have a white scale buildup in the gas valve outlet blocking the main gas flow. Take the valve apart and clean it.

Patio Heater pilot lights won't stay lit

crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.

One or more of those is the problem.

Oh...there is also a saftey case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)
