I have a craftsman die hard garage door opener with battery

Customer Question

I have a craftsman die hard garage door opener with battery back up (model 139.53918D). The battery has failed and I have ordered a replacement. I put a voltmeter on the battery leads from the opener, expecting to see 12-13vdc charging potential, but found no charging voltage. (opener is plugged in). Questions: Am I right in expecting to see a charging potential at these two plugs? If there is a fault within the opener that is failing to charge the battery, what card/part/part number do I need? Thanks

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond as typing, researching and adding links takes me time to do so please be patient and often I will ask you questions to narrow down the issue so do not rate me until we are done thanks.

This is a common failure on that unit. The logic board is bad. Replace this part to get the battery to charge again.
