The FX37SPT is a very reliable electronic ignition controller that is used in many gas appliances including boilers, fires, tumble dryers, etc. It is operated from 230V AC but it is available in other voltages as well.
There is a separate 30s pre-purge timer (FX30PPT) for those appliances that need one. It can be made compatible with many other ignition controllers. To replace a different ignition controller with the FX37SPT you may need a conversion kit. Check our accessories section to find the conversion kit you need for your ignition control. If you can not find one for your control, please give us a ring or complete our Ignition Control Specifier.
Important Notice: If replacing an FX37 that is more than 10 years old, you must check the connector on it as it could be different from the one on this control. All current FX37s have a green connector on them as shown in the picture on this page and require a mating half (also green) to be purchased separately if replacing a very old version of the FX37 or an FX30SPT.
An old FX37SPT or FX30SPT will have either a grey or blue connector that slides straight on and off the edge of the control. Should you have one of these, you have two options:
1. Purchase a compatible replacement FX37-P16. Probably your best short-term option, especially if you are not an installer.
2. A long-term solution (or if you are an installer) is to purchase the standard FX37SPT and a mating connector. Replace the old connector with the replacement one.
