Goodman split unit that heats instead of cools

I have a Goodman CPLE24-1C air conditioner that is remotely connected to a Janitrol AR24-1 (Goodman HKR-05) air handler. The unit cools very well for the first 30 to 45 minutes. Then it starts sending hot air out the air vents and the fan on the outside unit moves very slowly and the outside unit is hot enough to burn you if you touch it. Any ideas? Thanks Mark

Re: goodman split unit that heats instead of cools

Hi, Could be a run capacitor on the fan motor. They usually swell up and or leak when they go bad. If not, the only real way to test them it with a specific capacitor tester. A new capacitor would be cheaper. Make sure that the outside unit is disconnected from power before opening it up, try to spin the fan blade by hand. If it doesn't spin freely it may need oiled if possible. See above solution. Your problem is the fan motor though so if this don't do it, It will have to be replaced. If this helps, Please rate my solution. Thanks, kstfas

It appears the nuetral wire or improper grounding if its 120V unit. 220v unit will be a loose phase off of line one or two in panel box or unit connection. If this problem is common between other units it will be a factory design problem allow a single phase simulation to occur. Loss off phase would cause motor to slow down and overheat. Once outside unit is not functioning correctly where the outside condensor is not removing the heat through the condensor, you will get hot air through the inside mini split system.

Re: goodman split unit that heats instead of cools

Try this. Turn off the system and remove and inspect the air filter in the air handler for a restriction. If you find no restriction, go outside and turn off the outside unit by shutting off the disconnect switch. Turn on the system and keep the inside unit blowing for 3 hours. Then go back outside and switch on the outside unit. If the air conditioner blows cold air again it means that the inside coil is freezing up due to lack of refrigerant or something else. The slow moving outside fan could indicate that it is bound up and going off on thermal overload. Listen to see if the motor makes a moaning sound. Lubricate it if you can get to any of the oil holes in located in the end caps of the motor. At any rate you may need to call a technician. Good Luck

Goodman air condenser is humming but the fan does not come on

The most likely cause is the fan motor has failed. If it turns free then see if the capacitor is bad. Turn off the power remove the capacitor. Your local supply houses can test it for you.

Heating element does not come on when thermostat is set to heat. This is a Janitrol A49-10 air handler. Does anyone have some schematics for this unit ?

I do not have the schematic but if you take the upper door panel off and you will see what looks like a limit switch to the left and right. these are the fusable link connections to the heating elements. start there and that should be your problem

GSH13 Goodman heat pump split system is running a long time in cooling mode and will not cool below 74 degrees. A lot of condensation generated. The low side pressures 78 to 81 and high side pressures are...

Check sub cooling and super heat. the New ac units are very critical to charge. There is a charging chart on the inside of the cover to the unit outside. Check temp difference across coil. Should be 18 to 22 degress. If you have an ampmeter. Check the heat strips one 5 kw might be stuck.(sequencer). This would cause you not be able to pull down temp. Goodman unit are hard to charge to get the temp difference across coil. Feedback please

Goodman with 2 thermostats, freezes in summer, no heat in winter

is the system zoned? if so maybe the zoning control board to the damper motor is wired improperly. when a system freezez its because of 1- restricted air flow across coil, (maybe dirty filter) or 2-low refrigerant charge. again could depend on how its zoned.

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
