Hi there,
Glad I found this forum. I have a 2 yr old Intertherm M3RL 060A furnace with NO A/C. Problem is the blower speed is really high! And very distracting in my small trailer, as you can imagine. Looking at the manual, Figure 27, shows the location of the speed taps on the circuit board on the lower right. I see an orange wire connected to tap M1, no wire to M2, a blue wire to M3, a red wire to HEAT, and a black wire to COOL. Thanks for any help here on which wire/s to pull or switch over.
Gary
Need to lower blower speed on M3RL
Hi Gary,
M1= Blue
M2= Orange
M3= Black now on COOL
HEAT= Red
COOL= Nothing
EAC= Nothing
XFMR= Black from transformer
L1= Black from deck switch
Be sure that there is not a jumper across/between HEAT and COOL
Thanks,
Robert

Some people are Humbly Grateful, while some are Grumbly Hateful.................... Which one are you ?
Hi Gary,
You're very welcome, happy to help. That is correct wiring without a/c . IF there is a problem now, it will be elsewhere other than location of wiring.
Thanks,
Robert
