Why Webster Burner has no ignition?
- D
  Darlene BrownAug 21, 2025
  The Webster Burner might not ignite due to several reasons related to fuel and electrical components. It could be due to a lack of fuel, insufficient gas pressure, or a closed fuel valve, in which case you should check the fuel supply and valves. Another cause might be related to electrical connections ('spark, no flame'), so check these connections. Other potential causes include a defective pilot solenoid valve (replace it), incorrect positioning of the pilot or raw gas tube (check their locations), improperly positioned electrodes (recheck dimensions), or excessive combustion air flow (check the air damper position).

What to do if Webster JB2 Burner shuts down during operation?
- B
  Brian RhodesAug 23, 2025
  If the Webster Burner shuts down during operation, the problem could stem from a loose electrical connection (check and tighten connections), a loss of fuel supply (replenish fuel supply), or a limit switch breaking (opening), so you should readjust the limit switch.

Why is there no main gas flame in my Webster Burner?
- P
  Pamela BullockAug 25, 2025
  If there's no main gas flame in your Webster Burner, it could be due to a weak scanner signal, so you should clean the scanner lens and tube. Another potential cause is related to pilot, so you should readjust it. Fuel valve(s) not opening could also be the reason, in this case you should check the wiring to the valves.

What causes no main oil flame in Webster JB2?
- B
  Brittany RubioAug 26, 2025
  The absence of a main oil flame in your Webster Burner can arise from several issues. A weak scanner signal may be the cause, so you should clean the scanner lens and tube. Ensure the pilot is correctly adjusted. Check the wiring to the fuel valves, as they might not be opening. An obstructed oil nozzle or line could also be the culprit, so inspect and clean them. Verify that there's adequate atomizing air pressure by checking the compressor wiring. Also, ensure the compressor pressure is within the correct range by readjusting it. Finally, confirm the burner is level, adjusting as needed to prevent oil drainage into the vessel.

How to fix no ignition on Webster JB2 Burner?
- C
  Carl HamiltonAug 27, 2025
  If your Webster Burner isn't igniting, it might be because the electrode is grounded or the porcelain is cracked, in which case you should replace it. A lack of spark could also be the problem, so recheck the dimensions. Check for a loose ignition wire connection and reconnect or tighten it. Finally, the ignition transformer might be defective, so check it and replace it if necessary.

What to do if Webster JB2 Burner does not start?
- V
  velazquezmadisonAug 29, 2025
  If the Webster Burner does not start, ensure that the main disconnect switch is closed. Check for loose electrical connections. Verify that the operating controls are not tripped; if they are, reset the operating limits. Also, check the fuel supply and reset the switches if there's high or low fuel pressure.

Why is my Webster JB2 Burner making gas combustion noise?
- S
  Shelby BryantAug 31, 2025
  Gas combustion noise in your Webster Burner can be caused by several factors. The input might be too low for the burner components, so check the input and compare it to the rating label. "Rumbling" noises can occur, so readjust excess air. Fluctuating gas pressure due to the regulator not holding pressure can also cause noise, so check the regulator pressure and supply. High stack draft, especially at low fire, can be a factor, so stabilize the draft. Additionally, the diffuser might not be in the optimum position, so adjust its position in or out. Poor air flow distribution, resulting in an off-center flame, can also contribute to noise, so adjust the air straightener blade.

What to do if Webster Burner pilot is not detected?
- H
  Heather KnightSep 1, 2025
  If the Webster Burner pilot is not detected, it could be due to several reasons. The scanner tube might not be positioned correctly, so check its location. If a flame is present, clean the scanner tube or scanner. The scanner or amplifier might be faulty, so consider replacing them. Also, the pilot might be improperly positioned, so check its position. Incorrect gas pressure to the pilot could be the issue, so readjust the pressure. Finally, the combustion air flow rate might be too high, so readjust the damper.

What causes high CO at low fire in Webster Burner?
- V
  victor72Sep 4, 2025
  High CO at low fire in a Webster Burner can be caused by an improper excess air level, so you should readjust excess air. If firing gas, check the input and compare it to the rating label.

What causes high CO at low fire (con’t) in Webster JB2 Burner?
- A
  Adrienne ChangSep 6, 2025
  Continuing with the causes of high CO at low fire in your Webster Burner, consider these possibilities: a high stack draft, especially at low fire, so stabilize the draft. Poor air flow distribution (off-center flame) can also be a factor, so adjust the air straightener blade. The diffuser might not be in the optimum position, so adjust the diffuser position in or out. Finally, fluctuating gas pressure (regulator not holding pressure) can be a cause, so check the regulator pressure, sensing line, and supply pressure to ensure they are sized properly.
