There can be several reasons why your electric recliner won't go down. One possible cause is a malfunctioning power source. If the recliner is not properly plugged in or if there is an issue with the outlet, it may not receive enough power to lower itself. Another potential culprit could be a faulty motor or wiring within the recliner mechanism itself. Over time, these components can wear down or become damaged, preventing the chair from functioning properly.
