Good Morning, thank you for leaving such clear feedback, we would urge you to contact our office ( as names on here are not a direct link to our customer base. Your warranty is indeed 5 years, 2 years on the logic board, so any issues to do with that are and should be completely covered. The grey area is that the warranty is valid with annual servicing as per manufacturers guidelines and Guardian Doors quotations/T's &c's ( this is more for the spring tension ) to ensure the operator supplied isn't put under undue strain ( and therefore wearing it down prematurely ) With the number of power outages we suffer in Perth the logic bard can fail due to this, and as the door has operated without logic bard issues since 2017, we would have to take this into account, as logic board failure as a direct issue would usually show prior to this time frame. that being said, I would have liked the opportunity to explain Guardians stance and discuss a resolution with you, as apart from our product warranty, workmanship warranty, we also have a customer satisfaction guarantee - our end aim is to ensure that all our customers are happy/satisfied that Guardian has provided what they expect. I would also like to discuss your prior service as a Guardian Garage Doors service is not just lubricating parts, there are the whole heap of adjustments that are required, and if you felt that wasn't done properly, we would have liked to attend and assess the workmanship. If you would like to discuss the issue further, and allow us to work towards a resolution, please email your details through and you will receive a follow up straight away, We take our customer satisfaction very seriously and will always endeavour to find the absolute best solution moving forward. My apologies if this wasn't dealt with clearly at the time, once I have your details I can chase this up and work towards avoiding a situation whereby we leave a customer unhappy. Thank you and I look forward to hearing from you.
