Hi Sharon,

It is probably a Suburban NT-22.  If so, parts are still available:

If the damage is too extensive (for example rust-out), the under cabinet
ducted Suburban is the easiest heater to replace, as it can be done
without affecting the appearance of the trailer, and only costs about
$600.

For older styles of heaters (Hydro-flames, Panel-Rays, Day & Night's,
Carlson's, Marsh's, etc.) it then becomes more desirable to repair than
to replace.  The older units were built to last and rarely fail.  The
most common problem is LPG goo plugging up the gas control (disassemble
& clean), followed by water damage and rusting of the burner can
(welding shops can fabricate/duplicate replacements).  3rd method of
failure is a loose or broken thermocouple (tighten nut or replace).  4th
is a damaged gas control diaphragm seal, usually owner-inflicted.  In
most of these cases, replacement of the gas control with a modern unit
is the only choice.  5th most common problem is mud-daubers, wasps or
birds nests plugging things up.

All in all, no matter the age of the heater it is important to closely
inspect any heater every few months, use a CO2 alarm, and if using an
internal combustion air heater (no external air intake duct, just
exhaust ducting), make sure that you keep windows open to supply the air
consumed by the gas flame.

Best of luck,
RJ
