On a new installation this usually indicates that the unit has been incorrectly wired so please read the instructions supplied carefully and ensure that the unit has a separate live supply to the fan. This allows the fan to start the pre purge process and allow the boiler/water heater to ignite once the pressure switch makes contact.
Do not put the switch live with the permanent live as this sends a continuous feed to the relays and prevents the post purge from taking place. It also damages the relays after a while which results in early failure of the pcb.
Check fuses are ok – 5 amp maximum.
Isolate the fan supply and check if the motor can be moved freely – motor bearings may have seized.
Yes although we cannot offer a guarantee if this is not factory fitted. Our fans are designed so that the inner control tray can be removed as a sub assembly and returned to us for assessment and repair; a quotation would be supplied prior to carrying out any work.
Note: We do not offer this service for units over 5 years old. Replacement parts fitted by Flueboost carry a 12 month warranty.
Yes providing the product is returned within 14 days of purchase and in the original packaging we will re-stock subject to a 20% re-stocking charge.
The fan can be used but low voltage relays need to be installed to reduce the voltage from 240 to 12-24v then back up again.
Although our fans can run for 24 hours a day we do not recommend this as it will decrease the life expectancy of the unit. The motor bearings and windings should ideally have a cooling down period to prevent them overheating and burning out. Ideally the unit should be integrated into a time clock, thermostat or BMS as shown on the instructions supplied with the fan.
NOTE: If your boiler transformer or control is faulty or broken it will blow the new board so ensure these are fully tested beforehand.
Before installation of a new board check that the fan motor is not faulty by connecting a 240v live and neutral through the incoming mains and testing that the motor starts. If it doesn't start, do not install the new PCB as a faulty motor will cause the new board to blow. Please contact Flueboost for advice.
Checklist for fitting a new PCB
After ensuring the instructions above have been adhered to take the following steps:
Do not lubricate the fan motor as it has sealed for life bearings.
NOTE: Take care not to cause imbalance when cleaning the main impeller.
Please note, do not attempt any maintenance work on any electrical appliance unless you are a fully qualified electrician.
