pabloako1 asked:

I have a split system air conditioner, which when running on heating mode seems to be forming ice on the cooling fins and then cutting out after running for about 20 minutes. For the last 10 minutes of that 20, it doesn’t hardly blow out any heat. If I turn it off and back on again, it blasts hot air out for a few minutes and the starts cooling down again. I have checked the pipes and the insulation foam on the pipes seems to have got extremely hot and melted a bit. I have touched the pipe with the melted foam on and it is VERY hot and the other one is cool.
Any anyone help me work out what could be happening?

Many thanks

Paul.
