I'm sorry to hear you didn't receive an installation manual with your Chamberlain D2101 opener. You can usually find an electronic version of the manual online using a search engine. However, manual or not, it's always a good idea to have a qualified professional handle the installation of your new opener to prevent any potential problems due to incorrect installation.

It sounds like the door opener is set in Manual mode which requires holding the button to operate. This could also be a feature for safety reasons to ensure constant attention while the door is moving. Alternatively, there may be an obstruction on the door track or a sensor misalignment, causing it to not move freely without holding the button. If the problem persists, it might be more associated with a wiring fault or a problem with the control board. We recommend you check these potential issues. If none of these address your problem, it may be best to consider having a professional technician inspect it.

We're sorry, but without specific information about the product model and your location, we cannot provide a precise timeline. However, once you place an order for a replacement belt from Chamberlain, the standard procedure is usually quick. Just remember that shipping times could vary depending on the delivery service and your location. This is a general estimate and actual delivery times may vary.
