I have a Lennox G61MPV furnace and Lennox 2 ton compessor.

Customer Question

I have a Lennox G61MPV furnace and Lennox 2 ton compessor. Compressor runs as it should when thermostat calls for "cool", but furnace blower does not run causing coil to freeze up. If I flip the switch outside the furnace off for 10 seconds and back on, blower runs as it should until thermostat kicks out. when thermostat calls for cool again, furnace will not kick in again until I cycle switch again. There is no red led when blower not running when it should. After I cycle switch, led blinks every 5 seconds continually.

Sounds like you have an issue with it switching from heat to cool. The valve in the refrigerant line

Expert:  WCohn replied 11 months ago.

Its called a changeover valve.

Customer: replied 11 months ago.

Expert:  WCohn replied 11 months ago.

Its not something you can flip yourself its controlled by a solenoid valve powered by your thermostat

I want you to bypass terminal R and G at t-stat

Customer: replied 11 months ago.
do you mean connect?
it is currently in "cooling" mode, does that matter?
Customer: replied 11 months ago.
it just kicked out of cool. do you mean Jump r and g?
Expert:  Gaztech replied 11 months ago.

Put wire between, R and G, this will initiate blower to start and it should keep going

Expert:  Gaztech replied 11 months ago.

try that, will get back to you shortly

Sorry for not getting back to you, dealing with death in the family, do you still need help?

Customer: replied 11 months ago.
I'm very sorry for your loss!
thank you for getting back to me.
The problem is happening at my cabin. I'm going to be there tonite after 7pm. I bought a different t-stat, I'm going to try that before digging any deeper. If I put the t-stat in the "fan on" position the air conditioner seems to work fine. your thoughts?
Expert:  Gaztech replied 11 months ago.

I think your idea to replace t-stat is good, dont forget to shut power off before changing it,

Expert:  Gaztech replied 11 months ago.

Did it solve the problem? If you decide to continue let me know
