Commercial listings / need to repair combo infrared/gas dryer -Precision/M&R
« Last post by nightheron on March 31, 2025, 09:29:14 PM » I need help to fix an old 1989 Precision/M&R Combo infrared / gas dryer. It shuts itself off after several times in the morning. I need to figure out which parts to replace.
Do you know of anyone who works on these? Brian Flar of M&R used to diagnose this over the phone, but he retired. Does you know his phone # ?
I have the electrical diagram, and we used to check the fuses, the components of the Protectifier circuitry (ACF flame relay switchs, flame pak, transformer), thermocouples, Athena temperature controllers, flame rod, air vents, low gas pressure, high limit, air flow,.....
We would probe with the multimeter to check the circuits. We would bypass some parts to see if they were causing the problem.
It is too old for M&R to diagnose or supply parts.
It is a Precision gas fired vortex dryer CDG-20/1+9-476. This Precision brand was bought by M&R.
