Question about Heating & Cooling

Open Question

Goodman mini split

The Unit is set to auto but will not stay on to heat the room. The Auto light is green, the Pre-Def?? light is red and the On light is green. The room is probably 60 degrees and very cold. We just changed from air conditioning to heat....Is there something we need to do to change from air conditioning to heat. We changed the batteries in the remote thinking this was the problem. Any help would be appreciated. We have only had the unit for about 9 months.

SOURCE: Unit will not blow cold air after starting up for first time this season

you may need to remove the rear cover to examine what is and is not running. once you remove the back, start up the unit on a workbench. see if the fan is running and the compressor has kicked in. look at the larger or two tubes coming out of the compressor. if it is cooling a small layer of frost or condensation will appear on this " suction" line. if this tubing and the other one are approx the same temperature, then there is a freon leak in the system. Only an EPA certified technician can fill your unit. I am not familiar with that RED button but it mat be a reset of some sort. With the back removed see how it is connected in the wiring circuit. if you have the wiring diagram, please send it to me under my regular email address and I'll walk you through the troubleshooting procedure.

SOURCE: Goodman split not responding to remote

First turn the main power off to the unit at the breaker, wait about five min. and switch the breaker back on, then see if this solves the problem. In the instalation manual that came with the unit on the last page you will see a code of the red blinking light, this will tell you the most likely problem if not solved by switching the breaker on again.............Hope this helps

This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Good luck.

SOURCE: arcoair central heat /air conditioning unit

The blower motor kicks on when there has been a 24 volt control failure.

This usually means that a limit switch has tripped.

Most likely that would be a high temp limit switch or a rollout switch.

First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.

A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.

If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)

First, check filters.

My Kelvinator ESG21HRIA split system blew a fuse in the fuse box and now will not turn on!


to blow a fuse it must have a dead short ( probably vermin across live points)
when thee is a fault in a board (internal and external) it will run then shut down
I recommend that you have a kelvinator service technician come and check ti all out because if the system has been properly installed in the first place ( obviously not from troubles from installation), the units have an operation life span of more than 15 years

Goodman minisplit flashes on pre. Def. Wont start


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

Airhandler- the themostat is on auto/I understand cool,heat.emerg heat,The (G) terminal-then why heat mode or,emer heat fan blows?Only when i switch to cool mode the handler still want start up blowing...


the fan fill come on with the sequencer (stack switch you call it) it will also come on with the fan relay. on some goodmans the fan relay is the black box on the circuit board. use a jumper to jump red to green, this should bring the fan on sounds like you could have a broken green wire, try using a different wire instead of green

Do Goodman Split System fans turn off when the compressor shuts off? Is there a setting so the fan stops when the room reaches the desired temperature?


That is the job of the thermostat, but only if the "Fan-on/auto switch is set to auto. Look on your thermostat for the switch.

Goodman mini split model # wmh24-1a error code snowflake light stays on and 4th light from left blinks. i need to know what that means?


It's not an error. you have it set in auto mode and it is cooling. when it switches to heat the lights will switch as well. Set to cool only and it should go away.

I am looking to buy a mini split ac/heating 1 ton unit. I want to know how high from the floor does the unit have to be to cool and heat a 10 x 20 room?


Hi, when you buy your split system, the indoor unit will mount on your wall off off the floor a distance that the factory has made it for. With an 8' to 10' ceiling, it would be about 7' off the floor. This all depends on the refrigeration plumbing coming from the outdoor condenser to the indoor unit. It will tell you all of this on the installation kit for this unit, as the plumbing for the freon pipes are already pre-made for a certain height. A 1 ton, (12,000 btu) unit will have no trouble cooling a room of this size, so check with the manufacture on the height it will be.

Soleus KFGHP-09-ID Mini Split


This is normal operation for these styles of minisplits. The thermostat is not in the remote but is located on the return air of the indoor coil, so the air needs to be flowing in order for the thermostat to measure the rooms temperature. Set your fan speed to auto and the fan will slow down when setpoint tempurature is met.
