Air conditioner lights come on etc but won't go

you may forget to plug it.

slide out and spin blade by hand. should be able to tell if anything restricting rotation

Hi Kathleen King - Typically when the error code P1 displays on panel it indicates that the unit has a sensor error. I would recommend contacting a professional to accurately diagnose and repair the unit.

If you can access the pcb inside, check the mini glass fuse

my protemp sun-stream 60,000 btu wont ignite fan runs but igniter just makes niose

If unit has many years on it, you may find it cheaper in the long run to replace entire unit. By the time you pay someone to change it , with it being a closed system, installed valves to re-charge, etc., a new upper unit, is usually the better decision. Sorry. You won't need control box, ceiling assy .,etc., so it shouldn't be too bad. New lower amperage draw units are available as well but work just as good.

That hum making the lights dim as well I suspect sounds like compressor trying to come on. Are you sure you have a good 120volts coming in to RV?

Thermocouple could be corroded not allowing the millivoltage needed to keep the pilot valve open on your gas valve.( Change Thermocouple) Also could have air in the gas line from not being used for a period of time. ( Bleed Gas Line until air is removed) These fixes should only be performed by people competent in the operations of a water heater. Dangerous results can happen if not done right like carbon monoxide poisoning, fire, etc.

Remove the water tank and look or feel up to where the float is at and see if it is stuck in the raised position. This is what is keeping the light on and not letting the compressor start.

you must check the fuse of pc board.its a glass fuse and propably had burned,replace it,if the fuse is ok then is the varistor and you must get an expert to fix it.
