"small valve that can be pushed down"?
Hot water radiator with boiler (furnace) ?
Should be a water loop from boiler to bottom of radiator on one side, out the other and back to boiler. Usually a valve on one end or the other, sometimes valve is in basement. Sometimes handle on valve can come loose. You might be able to take handle off and turn with vice grips. Caution, if valve breakse or packing breaks you could get sprayed with hot water. Plus you'd really need the plumber then.
Check out the water "circuit" first. Look for valves shut off. Check pipes for heat from furnace to radiator. Hot water can be on pumped loops or sometimes gravity only feed. Could be one radiator on a pump that's not working. Also usually an air bleed valve on TOP of radiator. a little valve that uses something like a skate key to open and bleed air from the radiator. If it's full of air it won't heat. Sometimes there's a parallel loop of pipe that bypasses radiator so valve can be off and water will still circulate, especially if there are other radiators in series. Careful in this weather. If they are off in this weather they CAN freeze and break pipes or even the radiator.
Steam is similar, but probably a little more dangerous if you get a sudden leak. Steam goes up and condensate comes down.
Maybe try the tool forum for a professional plumber.
