Erben's facade and case remain today, but the pipes and internal mechanics were replaced with an E.M. Skinner organ in 1903. It was powered by a water-driven motor, providing a continuous flow of air. The church's consistory had written to the city requesting that water pressure be maintained on Sundays to allow the organ to function. In 1914 an electric motor was installed to replace the water. A smaller Echo organ was given to the church in 1927. In the mid-1950s the church decided to recondition the organ. After reviewing several bids, its Music Committee decided to award the contract to the M. P. Moller company, with a plan for further extensions of the organ. The reconditioned organ was dedicated in 1956 with a recital including Johann Sebastian Bach's Toccata and Fugue in D minor. Its console is still in use, after many emergency repairs. A Wicks choir division was added in the next decade. Another organ subcommittee was formed in 1978 to assess the progress since the mid-century restoration. Its major move was to replace the Wicks choir division, which had never integrated well with the rest of the organ due to a difference in powering methods. It was replaced with a Moller division in 1980. A 1990 committee was able to negotiate another deal with Moller for the completion of the plan.
