potterton profile 60e playing up again?
it broke down 2 months ago, new pcb fixed it, broke down yesterday, new fan fixed it, but now the main flame pulses and the burner pressure at the gas valve fluctuates between 8 and 14 millibar on a digital manometer, technical said check the flue, the inner duct was corroded so i installed a flue repair kit no improvement, its a standard horizontal flue, im starting to think its the guvernor fluctuating or the pcb having been straining against a janmmed fan delivering weak supply to the new fan, any ideas out there?
