SOURCE: 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 switch...in 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)

SOURCE: Nexgrill patio heater won't stay lit

I called Nexgrill technical support at 1-800-913-8999. They are sending me a new thermo couple to keep the valve open when ignited - so the patio heater will stay on. I needed to give them the serial number (inside the propane tank door) and fax them a copy of the receipt.

Hope this helps.

SOURCE: dyna-glo rmc-fa100a won't stay lit after releasing pilot knob

You should hold the pilot knob in at least 1 to 2 minutes, if it still goes out you need to replace the thermocouple. I hope this helps you out.

Why does burners and pilot forced off after burners are engaged


We get asked this question many times.

If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.

The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.

In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.

RHFE Rinnai 551FT gas heater is not working after 7 years


see this steps and fix it. God bless you
.
If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).
If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
To light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps:
Light the pilot:
  1. gasfurnace1.jpg Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.
  2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.
  3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Adjust the pilot:
  1. Remove any cap covering the pilot adjusting screw on a combination control.
  2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.
Test and replace a thermocouple:
  1. Hold the control knob to pilot and light the pilot as above.
  2. Unscrew the thermocouple fitting with an open-ended wrench.
  3. Set a multimeter to the DVC (lowest voltage) scale.
  4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.
  5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.
  6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.
  7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .
  8. Remove the thermocouple from its mounting bracket.
  9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.
  10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.
  11. Turn on power to the furnace and relight the pilot (above).
Adjust an adjustable burner air shutter:
  1. Set the thermostat to its highest setting to keep the burner running. Once the furnace has heated up, remove the burner access panel and loosen the locking screw.
  2. Open the shutter by turning it to the right until the blue base of the flame appears to lift slightly from the burner port surface. Then close the shutter until the flame reseats itself on the surface.
Clean removable burner tubes and ports:
  1. Shut off gas and power to the furnace.
  2. Unscrew or loosen and remove the tubes from the supporting bracket.
  3. Carefully clean the tubes with a brush or vacuum, making sure not to damage the burner ports.
  4. Use a stiff wire to clear any debris from clogged ports.

I accidently turned the pilot off and I can't get it to turn on Williams Model# 2001622


Turn the control valve to the PILOT position and push down and hold it in. Press the Ignitor Button and continue to hold the Control knob down, once the pilot lights. Wait one minute, release the Control Knob and if the pilot remains burning, turn the Control Knob counterclockwise to the ON Position. If after the burners light and burn for a few minutes, you can turn the Control Knob back (Clockwise) to the Pilot position (if you don't want the heater to come on automatically) and the pilot should remain lit.

Hope this helped to get you back up and burning.

Pilot light is ok burner will not ignite. the flame goes out soon as i release button.


You seem to have left a mixed message, as far as the problem is concerned. However, I think I have figured it out. But, first, let's go through the lighting procedure. To light the PILOT, you turn the Control Knob to PILOT and push the knob all the way in. While holding the knob in, you press the ignitor button. Once the pilot lights, you continue to hold the knob in for 30 to 60 seconds (which allows the Thermocouple to fully heat up), then you ease off on the control knob and the pilot stays lit. Right? Then you turn the control knob to ON and the Burner lights. But, that's not what's happening with your heater.

In a short version here's what I think you meant ... When you release the Control Knob from the PILOT position, the Pilot Flame goes OUT. It never has a chance to light the burner. Right?

If this is the case, couple off things can cause this. First, the Oxygen Depletion Sensor (ODS) is clogged with dust, lint and/or pet hair. Therefore the ODS sensor is reading the Oxygen level as Unsafe for operation. Secondly, the Pilot is dirty and is not allowing the flame to touch the Thermocouple as it should. The way to tell this, is the pilot flame curves upward, rather than being straight and lifts off the Thermocouple.

In addition to the two things I have listed which are the problem 90% of the time, there are 7 more. But rather than list all of them and how to fix the problem, I'm including a link to the Owners Manual for your heater. You can download and print is for now and future reference. Pay close attention to the Troubleshooting Guide. That's where you'll find the other 7 problems and their solutions.

http://www.desatech.com/manuals/Vent-Free%20Heaters/117001-01.pdf

Armed with all this information, I feel confident that you can Troubleshoot and solve the problem.

Please let me know how it works out for you.

Re Williams 3003622 Heater Please advise how to ignite pilot light.


You will first need to turn the control knob to pilot. Then depress the control knob button and hold it. Then press the push button piezo igniter several times until pilot lights or open pilot inspection cover and manually light pilot with match/lighter. You may need to hold the control knob for at least a minute. Then release the control knob and if the pilot stays lit then turn the control knob to on. If it does not light then repeat the process again.
