Question about Coleman Heating & Cooling
Sounds like a relay is acting up that determines weather to operate on 12volts dc or shore power

This could be the problem. It is more likely that the motor bearing is bad. Take the fan capacitor and have it tested. Or replace it, (under $20). Was the fan motor loud before this happened? Hopefully it is just the capacitor, the motor runs $60 - $100 and is a FUN to replace.

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the ac........plus your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $130....now you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know ..ray..email@example.com

“The voltage could be low – ”
a) Check the voltage between #1 on the
overload switch and the “R” terminal of the
compressor while it is not humming. This
voltage must be 115 volts domestic USA
models or 240 volts export/overseas models.
No less than minus 10% is allowable.
b) Check the voltage from “C” or “R” of the
compressor while it is humming (trying to
start). The latter reading will probably be
lower, but it still must be 103.5 volts
minimum domestic USA or 216 volts
minimum export/overseas models.
If the first reading is above 103.5V domestic USA and
the second is under 103.5V domestic USA, there is
too much voltage drop in the lines - a situation which
must be corrected for the air conditioner to perform
safely and satisfactorily.
2. “A capacitor could be shorted, weak or open.”
Turn the power off.
Caution – There is always a chance that a capacitor is
holding a residual charge, so before touching a
terminal, discharge the capacitor as explained earlier
in this booklet.
Remove capacitors, visually examine them and test
them per instructions given in earlier section on
capacitor testing (See page 9).
If the capacitors test OK, replace them and carefully
reconnect the wires. Be sure the wires are connected
to the right terminals.
3. “Start relay contacts could be open – ” if so equipped.
Turn off all power, then check for continuity with
ohm meter between terminals 1 & 2.
4. “Compressor start winding could be open or
Check compressor windings per instructions. See the
section on the compressors (See page 8).
5. “Compressor could be mechanically stuck.”
This very rarely occurs and when it does, it is usually
after a lengthy shutdown. This should be considered
only after all the above possible causes have been
positively eliminated. To free a stuck compressor, use
your hermetic analyzer according to the
