Customer Question

Potterton profile 80e ignition not working. Fan comes on, I think I can hear gas flowing, but no ignition, and so the fan / flow cuts off and keeps retrying indefinitely - any ideas?
Many thanks

You need to check the flue pressure switch.

The fan operates causing a pressure difference and activates the pressure switch this in turn sends a signal for gas and ignition to operate.

Sometimes the pipes get blocked and need a little blow through.

Here is a manual of profile 80e this shows the air pressur pipe on the drawing page 4 on the left hand side.
