Causes and Fixes A barrier that won't open, won't close or bounces: what's usually wrong and what to check. Every day this stays broken costs you more than the repair would. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Barrier stays up: loop or photocell thinks a vehicle is still there. - Barrier won't open: power, controller or the trigger device. - Arm drops or bounces: spring balance or arm length mismatch. Quick answer Most barrier faults come from power, a stuck loop detector, a blocked or misaligned photocell, a spring balance that no longer matches the arm, or the trigger device (remote, card reader or ANPR) not sending its signal. Many can be found with a few simple checks.

Usually the loop detector or photocell thinks a vehicle is still in the lane. Clear and check both. Why does the barrier arm bounce? The spring balance doesn't match the arm length or has weakened; a technician should adjust it. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
