1: Temperature Sensor Failure

Temperature sensor failure is a typical New Yorker boiler problem. A temperature sensor is an essential component of boilers. It determines the temperature of water in the boiler. 

Faulty wiring or short connection can lead to temperature sensor failure. There is no way to know about the condition of the water if this happens. 


This problem of the New Yorker boiler is easily detectable. The boiler will just stop showing the temperature. As the root of this problem lies in the wiring, you have to work on that first. Here’s what to do:

  • Check the sensor wire. Replace it if damaged
  • Check if the sensor is perfectly connected to the central control
  • Replace the sensor if the wirings are okay
  • Replace the whole control if the problem persists with the new sensor

2: Communication Failure

Communication failure is probably the most problematic thing you can face with your New Yorker boiler. The display board of your boiler is connected to the mainboard. 

This connection allows you to know about your boiler condition through the screen of the display board. If the connection between this display board and the main board fails, you won’t get any information about your device. 


In this situation, the first thing you will have to do is check the wiring to EnviraCOM terminals. The wiring in these parts may have gotten loose. 

Fix the EnviraCOM terminals wiring. If the problem persists, you will have to consult an expert.

  • Set the thermostat to heat
  • Fix the boiler circuit breaker if damaged
  • Keep the boiler gas valve open

If you are faced with this problem, then do not worry. Follow these points to fix the issue:

  • Make sure that the boiler is getting sufficient electrical and gas supply
  • Turn off the radiator and turn the radiator key to push out the trapped air
  • Pressurize the boiler if the pressure is too low
  • If nothing works, then replace the boiler

5: Blown Fuse

A surge of power can cause your boiler fuse to blow up. Your boiler won’t even start if there is no power supply. Check the fuse if it’s blown. If you find it in perfect condition, then the fault may be in the fuse wiring.


Replace the fuse if you have any problem with it. Here’s how to do it simply:

  • Turn off the power supply
  • Locate the faulty fuse
  • Get a similar fuse 
  • Unscrew and dislocate the faulty fuse
  • Attach the new fuse

Now turn on the boiler. Call a professional if the fuse blows again.

6: Boiler Switching Off

New York boiler switching off is a common complaint of old users. Imbalance of boiler pressure or clogged pipes can be the reason behind this problem. 


This problem can get severe, so as soon as your boiler starts to switch off automatically, try doing the following,

  • Turn off the boiler and clean it thoroughly 
  • Check if the thermostat is okay
  • Get a professional for pressure management of the boiler
  • Check if the power supply is providing consistent electricity

New Yorker boilers can make irritating noises from whistling, and buzzing to even banging. These noises usually result from faulty internal pipework, obstructions in pipes, and loose parts. No matter what the reason may be, no such noise is a good sign.


Here’s what to do in case the New Yorker boiler makes noises,

  • Flush all the obstructions and sludges from the pipes
  • Increase the air pressure and the flame rate
  • Tighten up every screw in the boiler

Your boiler shouldn’t make any more noise if you get these points perfectly covered.

8: No Spark

New Yorker boiler deploys showing STA 6 can be followed by sparking noises. This can indicate a short circuit within the boiler system. Such problems gradually lead to bigger issues. So do not wait before taking adequate measures.


Here’s what to do in case of sparkings,

  • Check for loose connections in the wiring
  • See if the ignition system is in perfect condition
  • Tighten up the loose ground connection
  • Fix the pilot spark gap

9: Faulty Pilot Light

Pilot lights are indicators of the activities of a boiler. It is a critical part of the whole device. However, the New Yorker boiler’s pilot light can sometimes mislead you due to its internal faults. Not fixing the pilot light will cause of your device not igniting and thus bring more problems. So deal with it as soon as possible.


Complete the following instructions:

  • Make sure that the gas, air, and electrical supply is smooth
  • Ensure that there is no clogging or blockage within any pipes
