Potterton Netaheat 16/22 pressure switch

[sanj001]

Hi,
Need some info plz
Had a corgi enginner round to fix this boiler. He said the air pressure swith had got stuck and he got it going again but said that there was no spares available. Just did a web search for switch and it seems that there is an alternative 64220403.
Is this correct and if so is it worth changing it?

Many thanks.
Sanj

Yes, the air pressure switch is still available, probably different maker (honeywell not yamatake) but compatible.

I find that its rarely the switch which is faulty but instead a blocked restrictor and/or loose flexible air tubes.
