There should be a reset button in the upper chamer next to the fan motor. In the middle ,push in on the center red button to reset it, this tripps because it says I,m not gettig enough air flow due to a plugged or dirty fliter located on the front cover or door.

If there are two wires to gas valve check voltage between these two wires while the furnace is going through a start up if you never get a call or voltage to valve your control board is bad, if you are getting voltage ,your valve is bad

I have a Intertherm MGHA-056ABFC-05 furnace and the burner will not come on?
The gas valve is seldom the issue. It is the Thermocouple, a relay or the control board. Gas appliances should only be diagnosed and repaired by a certified gas registered technician. In most countries that is the law.

I have an Intertherm MGHA 090 furnace. It runs short cycles never reaching temp. When the blower motor shuts off, the combustion motor stays running. If I leave the door open the furnace stays on.

My intertherm mgha is having pilot issues. The
The problem will be in what senses the pilot is lit. Either a thermocouple or maybe it uses an electrode and flame rectification. If it is an electrode you can try cleaning it. If it is a thermocouple you will have to replace it.
